Injectors upgraded, maf, and ecu and now won't start.

[Sil#2]

Ok so a nice Saturday with unexpected results.
97 ka-t
Just upgraded from stock injectors to Deatschwerks 550cc sidefeeds, N62 MAF, and enthalpy ecu that's supposedly tuned for this setup.

So tested the ecu first with stock injectors and maf and it started but ran rich.
Then swapped stock MAF with the N62 and it started fine with the stock ecu and idled ok.
So then swapped injectors with 550cc sidefeeds and plugged in the enthalpy ecu and now it doesn't start.
If I swap back the stock ecu it'll start, but I need to give it gas to prevent it from stalling and it runs horrible.

Soooo. Not sure what it could be. The ecu is supposedly tuned for the same injectors and maf.
The injectors were used but supposedly in good condition.

Is it possible the ecu is just not the right tune? I would think it should at least start. Help.

My first guess is mafs wiring!
Have you check codes yet? Verify the wiring try again, disconnecting the battery while doing wiring doesn't hurt.

If you still can;t figure it out just contact martin and he will be happy to help. GL

Daaamn. Thanks for the tip. I rechecked the wiring and I matched the wires up correctly but looks like a couple of strands broke. Retired and it starts! BUT... It runs like [email protected]
StalLs anytime I drop it in neutral. Bogs in 3rd and at times it'll just rev to 1500 rpms when I'm in neutral. If I give it a little gas it'll rev then stall. It'll even stall when I slow down and come to a complete stop in gear.

Could it just be a bad tune? Supposedly it's tuned for a similar setup and would hate to pay for a retune if it's not needed. Could it be a bad maf? My afrs are at 11 when idling and around 14 in boost. Thanks again.
