Qualicum beach,
BC_Canada
1g 1993 AWD 7 bolt
550cc injectors
268/272 cams
8.5:1 Cr
Forged internals
Water meth kit
Speed density, gm 3bar and iat
Aem wideband
Compound turbo setup 14b/16g
Trying to tune for 20psi (I'd do waaay more, but these injectors just can't do more than 20)
I bought an aem ems (30-1300) used locally for cheaper than I could find ecmlink for, however, being that I've never tuned before, I'm a bit inexperienced at this.
The old ecu had a aftermarket chip tuned to work with the old setup, seemed to be a good tune, would hit 10:1 Afr under all Boost levels till the injectors ran out, and would stay right at 14.7:1 in all vacuum levels, but timing was too agressive, and it would knock a bit at high rpms. Ideally I want to get to the same point with the aem ecu, but I don't know what the old ecu had so I can't copy it over to the aem.
I've input all the sensors, set the map sensor voltage as load (only way I could get any load to register), I can get it to idle, but if I try and accelerate, the afr goes all over the place, does anyone have a tune for speed density I could use a base to tune from? Or even just some pics of fuel tables, and boost compensation graph, and maybe timing table?
At this point, it takes like 30 seconds of cranking just to start it, idles ok but can't do anything else.
Would also consider trading for ecmlink
