7 wires, on the back of the ECU is written 3.2 6603

single sensor, its the one that accel sells with the DFI

DFI gen 7+ with wideband, Chevy main harness and v8 injector harness, also several ignition pickup harnesses. $1200

okay, i got it running BUT, it only fires every other time its supposed to (1of 2) or even more than that (1 out 4 times). according to my timing light (known works). i set calmap for 8 cylinders, injector order for 18436572 on bank to bank. I cant figure out why, its running through the factory...

ok, got it, any more questions ill ask, thank you

for anyone that might be able to help me, i am putting a F-body distributor (small cap HEI external coil) in my Malibu, i have the adapter harness to the GEN 7 ECU, but how do i go about wiring the 300+ ignition into this setup. I am using the coil that comes with the 300+ (only 2 wires, 1...

thats stupid. ill jsut cut out the notches.

whats the difference between the color plugs? arent they all wired the same way? so why do they need different plugs for different sensors? (GM style....1/2/3BAR).

IMO, the drag radials are a better straightline/track tire than a nitto will ever be, BFG's dominate the drag radial classes hands down and get short times of 1.5 in BBC nitrous G-bodies. The nittos may be better in the rain but honestly, who drives a sub 11 second car in the rain?

could someone set me up with a base map that i can do some fine tuning to for my BBC? Here's the specs: 533ci dart pro 1 heads 2.5x1.8 rectangle ports 2.25 intake valve cam is 244/256 @ .050 .632 lift 9.2:1 compression blower is not on right now. also, no matter what I do, my spark...

never mind that didnt work...

i am dealing with a similar problem, crank reads 50 degrees adavanced while computer says 10, this caused me to destroy a starter when the "start up term advance" added 20 degrees to the 50 actual degrees making 70 degrees advance while cranking..... here's what i am doing hopefully it will help...

improper tuning. depending on the cam. some other variables...blower surge...need a bypass valve....could be one of many things.

sounds good, thanks alot.

how do i wire it to make these 2 things work together? mr gasket has a thing on their website but it gives me the not found error.

does anyone know which wires i connect together to make my own Dual-sync adapter harness? i know the red and black are cam and crank +/-, are the white ones just power for the LED's?

what are your head and cam specs, i had this same problem with the small block in my malibu, 1900-2200 just plain leans out.

i dont see what difference it would make if you changed the parameter or the sensor....im sure your motor doesnt run at 16psi from idle to redline, when its below 14 psi wouldnt the sensor juat act like a 2 bar? if its not sensing the pressure it wont compensate? so shouldnt it work just fine...

you can use my motor to demonstrate if you pass me along a free sequential unit with all the bells and whistles :D

only thing i could think is that the o2 sensor is too hot or too far away, giving the exhasut more time to change its form, try mounting it in a header tube before the turbo, not in the down pipe.
