Just got in from a 5 hour tuning session!

Max: 490 WHP @ 25 psi dropping to 22

What its tuned at right now 467hp 404ft lb @ 20 psi strong

WOOOOOOO - no dyno sheet my dumb ass left so happy i forgot to take it out of the printer! I'll have him mail it to me


We ran into the same issue at first a few issues with the base map that was loaded, first the injector phasing was way off and lastly fine tuning to the dwell settings for the coils. But all is well, she spits fire and spins it in 3rd wooo

Videos uploading to computer now i'll upload them online tomorrow

Here is a video of him doing 485, just after this he did 490 then i told him to bring it down to the safe 450 range and he got it at 465 mark and left it as is. Then he setup my 2step & antilag.... I need better tires LOL

@boostmonger FIC 850 with DM fuel rail, 1 walbro 255lph. I just wanted to get it tuned now before i install my new aem water meth kit & bosch pump which i may run inline now.

So I have the same issue with the DM 1jz Ecu at the moment and would like to get it fixed and reving freely before I go spend money on dyno time.

anyone else have this problem with the AEMv2 ecu not being able to rev past 5500rpm ?

I see some talk about the Dwell settings mine is also similar to what you mentioned.

was this in fact the problem or was it the harness?

My issue ended up being basemap issue. The triggers/timing sync was off. I cant remember the #'s and my laptop is broken so i cant hookup to it right now... show me your coil/injec screen

Also IIRC the coils like to be at 2.0-2.5ms charge time (2.2 comes to mind) not 100% sure though as i have 1zzfe coils now
