2002 Subaru WRX – Install and calibration

Got an email from what ended up being a neighbor from me. He wanted us to install some stage2 parts to his Subaru at first and what this turned out was a long relationship.

We ended up fixing some issues we saw in the car, replaced couplers and exhaust flex pipe that had seen better days.
After the performance and maintenance parts (injectors, fuel pump, inlet pipe, etc) were installed and no leaks were present we proceeded to do a RomRaider tune on this vehicle. Loaded the car on the Dyno Dynamics AWD and proceeded to do the stage2 calibration on it.

Subaru WRX Dyno run

Runs are in 4th gear
Ambient conditions were 80F, 82% humidity and 30.03 baro
Correction factor (none) 1.00

Everything went so well that we continued to work with the client to upgrade bushings, rear wheel bearings and the last project was install some very needed gauges.  In came PLX Devices with their gauge pod and smart boxes to interconnect sensors.

Here are the AFR and Oil Pressure sensor video after the install. I said fuel pressure, that is what the description is labeled in the gauge, but its actually the oil pressure psi that is being displayed.

S2000 Turbo – Recalibration

A local friend came in to make sure that his newly bought vehicle was operating in optimal condition.
We loaded the vehicle on the rollers and proceeded to test to see how the AFRs, boost curve and power delivery was.

After careful inspection we noticed that we could move a few numbers in the VE table on the AEM v2 to reach optimal fueling conditions on the boost region.

2013 Scion FRS Turbo – Transmission work & Calibration

2013 FRS Turbo, rectifying work from another shop on this manual transmission. Seems that synchros went south on this transmission, time to open her up and see what is the verdict.
After inspection 2 and 6th gear are the only ones that look decent. Synchros, hib sliders and the other gears will have to be replaced in order to bring this transmission right away. Well time to build a bulletproof one down the road.  As for now we also fitted the transmission with a new SPEC light flywheel.

After the install of a good working transmission along with the SPEC Flywheel, it was ready to hit the street to see how it feels.  Oh yeah Amsoil synthetic 75W-90 was added to the mix.  Shifts smooth as butter, Highly recommend adding this oil to your differential or transmission.

211whp run in the peach color was a run that was done back in 3/9/17.

Both of these runs were done at the same boost level 9psi, but the one the one that generated 218whp / 248wtq (purple lines) was done in a more hot ambient as per descriptions in the video.  What a difference a proper working flywheel can make and when the right care if given all around to the the vehicle.

2013 Subaru STI – Stage2 Calibration

Was the first day of fall, but with the ambient conditions that were present you would not think so.  Another hot and humid day in Kenner, LA.  We were working today with Scion tC as we installed a transmission on it and was adjusting the clutch on it and driving it on the street.

Got a call in the morning with a client that was wanting some one to look at his 2013 Subaru STi as it was not performing up to its standards.  Managed to squeeze the client in at noon and told him that we usually calibrate the cars at nights since it gets really hot in the shop.  He was coming in from MS and driving thru town on his way to Lake Charles and decided to call us to help him with his ride.

We moved cars around at the shop and got the AWD Dyno Dynamics ready for his arrival.  Placed the vehicle on the dyno and got it ready to see what we could do to help matters.

2013 Subaru STi with stage 2 mods:

Stock engine / Cobb intake, APv3 /Grimmspeed Upipe, TMIC and catback exhaust
Tial BOV with EWG / Air pump delete / Cobb Fuel pump

Ambient conditions were 103F / 43% humidity and 30.03 Baro
Test performed in 4th gear

The vehicle was previously etuned and the client wanted a dyno calibration instead so we proceeded to accomodate him as he had some DTCs present that needed to be taken car of which were affecting his fuel trims and his over all WOT fueling.

Before the dyno pulls were done we checked the oil level and also discovered that we needed to add a quart of oil to the engine. In comes some Amsoil XL series 5w-30 to the rescue.

Before and after resutls from the tuning session.  261awhp and 288awhp was achieved.

Dyno jet simulated number vs boost which just hit 20psi and tapered to 16psi.
In conclusions the client was very happy and we thank Chris for trusting us with his ride and having patience in this hot and humid day which was not easy day to calibrate an engine.

2013 Scion FRS – Kraftwerks

On Saturday got a chance to calibrate another Scion FRS that was forced induced.  This vehicle had previously visited our shop on the later part of December to get a baseline done.  On that given day which the ambient conditions were in the 66F with 65% humidity.
The owner had just fitted the vehicle with a Kraftwerks supercharger set up.
No other mods were present besides the supercharger kit on this vehicle with a Automatic transmission.
On that given day the best number that came out was 214whp (with the Kraftwerks ROM) and it was tested in sports mode in 4th gear.

Fast forward to Sept. 16th with ambient conditions in the 97F, 52% & 30.10 baro, so a rather humid miserable day and the best that the vehicle managed to baseline line was 189whp @ 12psi.  Now that we got our baseline we plugged the EcuTek Protuning kit and proceeded to start from scratch with our own calibration to improve the performance from that Kraftwerks ROM file the car was using.

 

Needless to say that with movements in Fueling, timing advance and cam timing we managed to improve from the numbers on the tuning day and also surpass the numbers from the colder December day back in 2016.  Very happy with the numbers and can not wait to calibrate this car once again when the owner starts adding UEL header and exhaust components to free up some low end torque.

2015 Subaru WRX – Stage1 mapping

Got a local friend that hit me up asking me for some help on his Subaru. He has issues of the car stalling at stop signs and stop lights. Got the car in and looked at the plugs and they were fine.

Checked and see and this car has a AEM intake with box but with no calibration.  Seeing this we ordered a Cobb Tuning APv3 and installed it.

Made some adjustment on the dyno over the OTS stage 1 calibration and was able to find a little power enhancements and now no more stalling on stops.

Ambient temps at the tune 92F, 70% humidity and 30.03 Baro.

Test was made in 4th gear.

Before an after the Protune, fueling was very inconsistent with the oem calibration and now its dialed in. Managed to make the turbo spool a bit quicker
as well with the calibration move.

Baseline pull in blue and then the other two lines are after the calibration on stage1.  These are Dyno Jet simulated numbers.

Thanks again Forty for trusting us with your ride!

2005 Subaru WRX – APv3 Protune

Good day to you guys, well in another hot humid day in Kenner, LA we had a client come in from Biloxi, MS.  This was his first Subaru he has ever owned and wanted to make sure the car was running good from the previous owner that had the vehicle.  The vehicle is a 2005 Subaru WRX, with these list of mods:

  • 2.5L Built bottom end (forged internals)
  • 2.5L head (HD exhaust and intake valves), no avcs with TGV delete
  • Blouch td06-20G (BB)
  • Injector Dynamics 1000cc
  • Fuel pump
  • Larger TMIC
  • Turbo back exhaust
  • Cobb Accessport v3
  • Cobb intake
  • Southbend clutch kit.

As our usual way to start things is getting the car on the rollers, strap it down correctly and place all the necessary sensors needed for the calibration.  As we discovered after we made a 3rd and 4th gear WOT sweep as soon as the Blouch turbo would come alive our AFR went up with the boost and as many know that is not the way to keep a EJ255 motor happy and in one piece.  That meant we could not even do a full RPM run and we had to get to mapping the engine straight away.
As soon as we started getting the fueling down to the right range we started running into another issue.  As the boost started coming in as we made a sweep usually around 5000-5500 rpms the car would experience a sensation as the clutch was slipping.
Lowered the boost to wastegate spring rate and that did not help matters that much either.  Asked the client once again the clutch was on the car and he said that Southbend clutch was only in there for a few months.
We could not get that distinct smell of clutch when we were making the runs since the car was also exhibiting a little oil burning smell and that was indeed masking any other smell in the dyno room.

We now decided to get it off the rollers and do some street testing to make sure it was not the dyno giving a odd load to the vehicle (which I knew that was not the case) during the test runs.
Well as we tested on the local highways sure enough, right at the same psi and rpms as the dyno the car would quickly rev up in the same zone where the vehicle starts making its peak WTQ.  In any case managed to properly map the engine for where we could on the psi where it did not slip which in this case was around 13psi. Oh yeah the client tried to do a weak little launch and that only solidified our initial hunch that is was a clutch issue that we were experiencing.

So for now we are going to be ordering a new clutch kit for this client and installing it. Once the clutch kit is properly broken in we are going to re-visit this calibration session.

So stay tuned to see where this nice Blouch 20g ends up making once the bugs are sorted it out.

Thanks for checking out our blog posts.  Cheers

2005 Subaru WRX – Costa Rica tuning

Talking to an associate of mine in Panama, he indicated that there was a technician over in Costa Rica that needed some help fine tuning a Subaru WRX.  After talking to this tech. in Costa Rica, I decided to give him a hand and try to help his client out.  The Subaru had some mods and there for needed to be fine tuned.

The mods were SF Intake, Downpipe and CBE, STI Pink injectors, FMIC and VF22 turbo.

So with a few iterations on the Cobb Accessportv2 and starting with a stage2 91 octane map, since the fuel in Costa Rica has less octane rating then the pitiful California 91 octane.  That is what was used as a starting point in this remote tune.

Good to have my first remote tune in the country of Costa Rica.  Special thanks goes out to Sebastián owner of InterlinkPZ & to Murruco for trusting in our tuning abilities.

Review from Facebook page:

Sebastian Cervantes Bedoya reviewed Corr Performance Tuning — 5 star
Excelente!!!
Muy buena atención la de Alberto, gran conocimiento. Se preocupa por que todo quedé como debe ser.
Se le agradece la paciencia!!

Panama Tuning Adventure – Part2

The other days of being here we had some set backs with the cars. This 2005 Nissan Armada did not pose any problems as it was fitted with a UpRev calibration to get a little more power and fuel economy.

A gain in both WHP and WTQ were added to this vehicle.  The chart for this tuning session will be sent to me at a later time and I will update the blog.

This 2016 Mustang 3.7L v6, A/T was next on the slate to be tuned.  Mods on this car was AirRaid intake and MagnaFlow exhaust system.  Tuning system employed was HPTuners.

This was my first go a tuning a HPTuner system on a Ford Mustang.  I was thankful enough to have the help from 3 other competent domestic tuners that guided me thru the process of tuning this new ECU.

The ECU on these years like also the Coyote 5.0L motor employs speed density tables instead of MAF scalar tables like the earlier models.  I have to say it was quite laborious to tune these ECU, I have a ton to learn still but at the end was able to make some improvements on the performance of the vehicle.

Blue line is the baseline from where this car was tested before and the red line is after the mapping with HPTuners.

Test were done in 3rd gear via sports mode.

After the Mustang these two other vehicles were slated to hit the dyno and make some decent power but had some mechanical issues that came up and we were not able to finalize the calibration on them.  All these vehicle you see and there are like 4 more in the shop (that I did not take a picture of) that all sport a Haltech engine management system. I will be coming back to Panama soon enough when they are once again ready to be calibrated.

As always had a great time with my family at Taller NB in Las Tablas, great group of people to work with and will be back here soon enough.  As for now signing off from hot and humid Panama

Panama Tuning Adventure – 6.26.2017

Its always great having the opportunity to return to my country and help out my associates in getting their clients’ vehicles running correctly.  It also excellent that we have Copa Airlines flying direct from MSY to Panama, trip is only 3:30hrs.  Apart from that, it is always hard leaving the family and rushing out the door at 4:15am to catch a flight.

Waiting at the terminal I was greeted with a celebration as that same day was the actual 2 year anniversary of Copa Airlines having direct flights from Louis Armstrong airport to Tocumen Panama.  Flight left on time and arrived in Panama at the scheduled 10:50am.

Met my friends at the airport and was welcomed by the usual gridlock traffic that the capital of Panama is famous for.  Drove to a performance shop to pick up some VP Race fuel and saw a Honda tech that is famous around the country for his high horsepower projects.  This time was no different as Vicente was working on his Honda Civic with Kseries swap turbo.  This should be a nice little monster once its all said and done.

Well since it was past lunch time we had to stop by to get something to eat before the ride out to the country side.  Stopped at this mall and ate at a place called Lenas y Carbon and had a nice steak, along with some nice sides and a chicken soup called “sancocho” down here.

Arriving at Taller NB in Las Tablas that night was greeted with 2 very nice 370z waiting to be protuned via UpRev.
The red one has some Stillen Gen3 intakes and Greddy catback exhaust.  Final numbers were 298whp and for all you dyno jet people that translates into 334.5whp.

ARC option was added to this vehicle.

 

Next up was a 2009 370z with AdminTuning intakes, soho performance exhaust with test pipes.  This car with the addition of the intakes it would not idle decent because of the great breathing intakes that this car possess now.
After a few tweaks on the UpRev ROM we were able to get the car to idle great and also make some considerable gains.  Apart from the UpRev ROM both cars were fitted with the ARC system.  At the end of the night we had 2 very satisfied clients going home.  Final numbers for this black 370z was 306whp or 342.72 dyno jet numbers when the translation is performed.

ARC 2Step in action after the tune was finalized.
