Tuning Technologies maps the EVO X
Tuning Technologies maps the EVO X
The EVO X in this post belongs to forum member MYFIRSTEVO. I have known Alvin since we first opened Tuning Technologies and he was gracious enough to lend me his car for a week or so. Alvin previously had a 2003 EVO VIII with everything from the stock cammed turbo to a GT3076R on race gas, so he knows how a properly mapped engine should feel. I will let him tell you guys about the before and after driving experience as I had limited pre-mapping street time with the car. Onto the good stuff.
We have been working very hard in terms of R&D on mapping the new EVO X. As many of you may already know, the factory tune on the X is incredibly rich, even after applying the new factory reflashes. The initial dynamometer pulls show the AFR’s going sub 10:1 by 3900 rpm and never recovering to a reasonable AFR. The boost peaked 22psi on average and tapered down as low as 12.24psi at 7100 rpm. That’s about a 10psi drop from peak boost which partially explains the lack of powerband and the excessively rich AFR’s.
Average ambient temperatures were over 100 F and humidity was at about 13% average during the tuning.
IMPORTANT: THIS CAR HAS ZERO POWER MODIFICATIONS. BOUGHT STRAIGHT OFF THE DEALER LOT NEW AND HAD 16xx MILES ON THE ODOMETER.
Here is a breakdown of RPM’s ranging from 3200 to 7500 with corresponding results. I was very happy to see the new mapping produce gains across both curves, even below the 3200rpm marker (not listed).
Horsepower
3200 +3.0 hp
3500 +8.6
4000 +24.08
4250 +27.2
4500 +38.3
5000 +37.11
5500 +27.52
6000 +33.43
6500 +43.9
7000 +37.12
7500 +19.0
Torque
3200 + 5.03 lbft
3500 + 12.8
4000 + 22.6
4250 + 31.21
4500 + 42.98
5000 + 38.16
5500 + 27.0
6000 + 29.9
6500 + 35.3
7000 + 27.79
7500 + 14.8
This translates into huge additional powerband along with a stock EVO X that is much more pleasurable to drive.
Spoolup was considerably improved through extensive testing and tuning of the intake and exhaust MIVEC system. On the before and after graphs at 3600 rpm, the baseline boost was 18.31psi and 21.43psi respectively. That’s a 3psi increase in boost during spoolup! I put in several days (literally) tuning this car and spent the better portion of a day strictly on this aspect of the tune. I know that if the weather was a little cooler the car would have easily clipped the 300whp marker.
The new ECUboost control is pretty trick. There are two wastegate solenoids now and they must be in harmony to work effectively. We custom tailored all the wastegate and load tables while maintaining the factory safeguards, checks and balances. The boost limit/fuel cut, high and low fuel and ignition mappings are still in full time use if they are ever needed.
In the end it’s EcuTEK’s FlashCANEVO that makes all of this possible. The software is very intuitive but best of all it works flawlessly on the X’s new CAN system. The map tracing and data acquisition features are priceless along with the 16hr a day support you receive from them. The level of adjustability is constantly growing and that’s what we need to take full advantage of the X’s potential. If you have an X and want it tuned, give us a call and we will be happy to give you all the details.
Overall this EVO X was a blast to tune and really challenged me as a whole. I expect to see great things once we get some basic modifications like a full exhaust, intake, IC piping and with a lil luck.......some cooler weather.
