Spent a few hours tonight trying to get the seven to idle correctly, without much luck I hate to do this but I have a few questions regarding the idle.

Setup

E6X
550/1600
3Bar Map
S5 TPS
No BAC

Running Hitman basemap for 1600cc secondarys and upgraded turbo.
Timing is set dead on

I can get the car to idle awesome holding the throttle at about 2%, will idle right around 900 to 1000. Without any throttle it want's to idle around 200-400rpm just barely staying alive.

Ive tried increasing and decreasing fuel in the main fuel map at 500-1000rpm with no changes whatsoever it seems, except either way to an extreme it will stall. As well I've tried enabling the zero throttle map and leaning or richening it up some to no real avail.

With no BAC I've attempted to bring the idle up with the screw on the throttle body which for some reason didn't do anything even though I only need the throttle open 2% for a steady acceptable idle.

What is general way to begin setting the idle?

Are my problems because the lack of the BAC?

It doesn't seem like a big deal to put it back on at all except for the fact between taking it off the motor and going to see about hooking it up to the haltech tonight it seems to have lost the adjust screw?? oh well.

Any insight is greatly appreciated!

Whoa.... two lessons to be learned here, when your map signal wire has is open and your haltech thinks its reading 30+psi and dumping in gallons of fuel, and you breath a 90/10 mixture of fuel and air all day.....your going to get retarded.

Second.......the throttle stop screw is on the back side of of the throttle body, not the front.

Thank you haltech forum!

 

which signal wire u are talking about?

 

which signal wire are u talking about?

 

I guess he answered his own questions

 

Yup! anyways, the yellow signal wire to the MAP sensor. I'm not even sure how the thing was idling with the data page displaying 30.6lbs positive pressure.

 

I do have another problem, though if if its related to anything I'm not sure

In Trigger diagnostics

Home Count is ALWAYS 12, should be counting 0-7?
Trigger Count is usually jumping between 46 and 64 OR 80 and 96, not really counting, should be counting 1-255?
Trigger before last home count is ALWAYS 0. should be 2?

I have a steady 250rpm reading, have spark off all coils and fuel, and even runs okay when I can get it started, never want's to start cold though, messing with corrections to try correct this to not much avail just yet.

Another odd thing, it always really wants to kick over when the lead one wire is held an inch or two from the coil. I searched and found another thread relating to this anomaly but they came to no conclusion.
