Recently switched from Hondata Kpro to AEM Infinity, so started from scratch with a new tune. I made the switch mostly for all the fail-safe features (oil temp, oil pressure and fuel pressure setup so far)....but the car seems to be running a bit smoother and making a little more power and torque, so Bonus!


Quick rundown of my setup:
Full-Race prostreet turbo kit w/GTX3576
Stock 2.2L bottom end
URGE turbo head
FID 1200cc injectors
SOS twin pump surge tank (450 in tank, twin 320's in surge), 8an feed / 6an return
SOS Flex-Fuel setup

Most of the tuning was done in 4th gear and I'm running a Puddymod diff w/3.90 gears
Full tank of E85 (we were reading ~E78 from the ethanol sensor)
Boost is at ~14.5psi
Tuning was done a mile above sea level (Denver) on a 2wd dyno, so there are some correction factors
We were seeing 103 degrees inside the shop during tuning




I haven't had a chance to drive it since the tune, so no initial impressions. Also, I'm not chasing #'s or here to brag...just wanted to post up about my setup and switch to Infinity

Scott-

 

question,, are the two set ups with Kpro and AEM the same? same tuner?

 

Setup (besides the swapping of the ECU's and associated parts/sensors) are exactly the same.

Tuner and dyno are different from my previous tune

 

Ooopps.....totally forgot that we switched from the OEM IAT sensor in the IM to a GM IAT sensor now mounted in the lower charge pipe (post Intercooler)

 

what was our old numbers with the hondata?

 

603/430 on Hondata

 

So it's around 480 @ 1bar uncorrected?

 

630 whp on 14.5 psi? Hmmmmmmmmmm

 

Damn.....forgot to ask for the uncorrected graph :/

 

All I can do is post the info that I know....obviously lots of variables with elevation, dyno, etc

Yes, we were getting spark blowout at 17psi so had to turn it down. Unless the SOS 3 bar MAP sensor is reading incorrectly (or the values for the MAP were entered into Infinity incorrectly...but that is a little beyond me), we are at 14.xx psi
