#Evom tuning sheets install#
Recently I got hold of an EBC (Blitz) and managed to install it. I noticed that the boost gauge (20 psi gauge) does not go all the way to the end (which confirms the dyno reading). I was impressed with the result, the car felt much better than before and seems to have a continuous acceleration (instead of a power/torque drop felt during a gear change before). So, after my own diagnosis, I revert the auxiliary device check to the pre-tune setting to eliminate the CEL and went for a drive. However it would be nice to check the auxiliary checks to ensure that it was equal pre and post tune.

My hypothesis is that the tuner copy-pasted the base tuning from an evo 7, and fine tune the ends, which I honestly don't see a problem with if it wasn't an overnight work (2 days and one night) and did not charge for a full tune. The tuned rom was based on the EVO 7 rom, which I thought was a bit odd, since it had an EVO 8 rom previously. Compared to the previous rom that I had pre-tune (an EVO 8 FQ300 Rom), the pre-tune rom did not have the EGR check enabled - for the simple reason that the car has no EGR.
Upon further checking on the ECU rom, I found that the reason for the CEL was that the ECU failed to detect an EGR component in my car. When I got home, I resetted the ECU, but the CEL error still persists. When queried about the boost reading on the dyno sheet vs what I requested earlier (17 vs 21 as requested), I was told that the car does 21 psi on the road and somehow only shows 17 on the dyno (I thought that was a bit odd). I was told that the CEL refers to the EGR system, and asked to return the day after for further diagnosis. I recycled the power several times to no avail. Additionally the car had a CEL (Check Engine Light) on, from the moment that you turn the engine one (prior to starting the engine). Upon getting the car back, I was presented with a dyno sheet that reads the power at 176 kw and a peak boost of 17 psi and oscillating between 15 and 17 psi throughout the rev range. I then agreed to get the car tuned for about 21 psi (+- 1 psi), which he said would yielded about 200 kw at the wheels. He mentioned that the boost control function could be controlled by the ECU, so that a boost controller is not really necessary to increase the boost. At that time, I said I will wait until I get a boost controller to provide a better boost control than stock. The specialist also checked the turbo wheel and found no shaft play.Ī couple of days later, I was contacted by the tuner of the 'dyno day garage' offering their service. I went to a local car club dyno day and found that my car (Evo 8 with intake and exhaust) was only getting 128 kw at all wheels.įurther on, I went and get the car checked for boost/vacuum leak and cylinder compression from an 'evo specialist' and found that the compression was spot on and there was no boost/vacuum leak. Hi Guys, I just would like to get your opinion on the tuner option that I need to take based on the following:
