AEM F/IC hiccups under boost
I got the Dezod S1 kit with AEM F/IC - i went to RIPP mods in staten island for a tune yesterday and had Perry tuning it. The AEM keeps throwing crank shaft sensor codes and makes the engine "hiccup" under boost. Perry got it so that it doesnt happen too much but it still does it at higer RMP. Also with 550cc injectors under 8.5psi the richest he could get it could get under boost is around 12 afr.
Any suggestions?

Its like it misfires / detonates. Say your on it - full throttle and pulling hard, it feels like im hittin the breaks for a second. When this happens the CEL comes on throwing a crank shaft position sensor code.
Last night i figured out that this almost ONLY happens under WOT. The timing on my map maxes at a -24 like any other map for the tC, so i dont think its too retarded.
Which wire in the PnP Harness is the wire for the uego input for data logging?
- It also did this with every map that i have tried on it.
Im also running NGK 1 step colder plugs with a 32 gap
F/IC is running version 3

So wait.............You have -24 degrees of timing?

so i paid $400 for a half ___ tune?
So what should timing be at? Im guessing at lower RPM a little less than at high RPM since boost only increases at about 3500 rpms. Ill set timing to -19 @ redline, slowly increasing from -16 at 0 rpms (this is under 40 load)
So really i should try ^ my tune see if i get the same problem?

So - i found out you can change the intervals on the sides of the tuning software. That makes things easier. The tuner at Ripp must have change the intervals so when i looked at it on my laptop everything looked off. Ill be testing that theory later on today.

if not that makes things a bit more complicated.

I would have expected the same! for whatever reason looking at the map they tuned for me it looks like spark is retared -22 @ 30 PSIA, and only -3 @ 24 PSIA. Plus my fule map has litteraly no gas @ 24PSI
