I've tried using a few of the stock 4.3 files, one of which it's currently running on. I just can't figure out why it's running rich and I'm 99% sure it's because it needs a file that is tuned...

Hello,

I'm looking to have a .BIN file tuned for my application. I have the capabilities to burn the stock chips, but I am not experienced enough to do the tuning myself. I'm willing to purchase,...

Thanks for the reply! I have tested the magnetic pickup and gapped it .008" from the reluctor, it was also known working before the swap. The wires to the module are all good, redone with audio grade...

I tested coil resistances, which are still within tolerance, and it is getting 12 volts. I also swapped in a different coil just for testing, and still nothing. Cap and rotor are good, and the plug...

The injectors do pulse and seem to spray a nice cone shape as they should.

IIRC, the MAP sensor read at exactly 4.8volts- pretty close to sea level here. TPS is set at .51volts, and does increase...

Ignition module should be fine. I had one BWD module from Advance Auto go bad instantly. Then I used a junkyard GM module, which is what I had it running on.

Now I have a Duralast module from...

I just swapped a GM TBI from a 4.3 V6 to the 4.0 in my AMC Eagle and I am at my wits' end with this. I put the wiring harness together myself, and I intended to control fuel and...

Interesting, I didn't know you could wire the MSD up using the GM module as well. I thought it was either one or the other. I'd be very interested if you could remember exactly how it was done.

I...

Hi all,

I'm new to the forum, searching for info regarding the GM TBI from a 4.3 V6. I have an AMC Eagle that is my daily driver and I've wanted to fuel inject it for the longest time. I initially...
