can't get it to idle :(

Alright guys,
I finally got the engine to start, but it won't idle on its own.
I'd have to hold the throttle almost WOT for it to start. Once started, I'd have to hold the throttle slightly open for it to idle. Here are the stats:

550/1680 injectors
DIS-4 on the leading plugs, DIS-4 Plus on the trailing plugs
Aeromotive FPR, 30 psi at zero manifold pressure
haltech E11 v2

It is running very rich. Looking into the O2 sensor hole, I can see wetness in the downpipe.

The BAC is not wired. I did adjust the idle screw on top of the throttle body to no avail.

Any ideas? Here's my map for your critique. Thanks.

geez, a weeks gone by and still no help for this guy?
You might try the haltech section as it does sound like a tuning/map problem.
I wish I could help you but I pay someone to do my tuning and I'm on microtech.

Remind me to post my map for you. I have the identical setup to you, including the DIS-4's. I'm not using the BAC at all.

I guess the map i sent you didn't work?

also, you may want to crack your throttle plate set screw... I am sure we all have done that to get it to idle, even with the BAC or not

Si senor,

Cranking is about 6.5 ms and idle is about 2.3 ms......


I'm fighting another problem now. Can't get tach to work with pwm1 on the haltech.
Dash lights work ok, though I can turn the HVAC fans on without having the key in the ignition. I used granny's speed shop procedure to ground the black/blue wire....didn't work.

Does the haltech have a pull up for the tach channel you are using?
