I dont know what all info the ECU genius's need so I will have to update this as we go.

Stock ecu, ID 1000's installed and resistor box removed. On 93 pump only.

Scaling set at 860

Voltages

6.01 - 3.456
7.98 - 2.592
10.03 - 1.656
12.01 - 1.224
14.06 - 0.984
15.97 - .816
18.02 - 0.696

Takes a good 5-7 cranks when cold, plus holding the gas down to get the car to start. But once it starts its perfectly fine. Zero warm start issues, etc. Low and mid trim are within 3% of zero and I really just dont understand why this thing requires so much help to start??? Its annoying...

What other info is needed to help diagnose the problem?

 

db could address this im sure

 

...who do you think tuned it..

still having issues.

 

Has it always done this since these injectors went in?

I know there is a "cranking primer initial pulse" map and others that deal with cranking and IPW.

Maybe some of these can be tuned in to get it to fire better for ya

 

Always been bad. Let me take a screen shot of some of the parts I think maybe relevant.

 

 

I hope that helps some one haha

 

Checked coolant temp with car having been off since yesterday

coolant temp - 109
mas temp - 102
gm ait temp - 106.7

 

damn , did you ask big al yet?

 

hes next on the text list lol


...and sent

 

Nothing you do to any of the tables will fix this issue... learn to love it, as the injectors are awesome once the car starts... try reading This thread

 

Wouldnt lowering the IPW adder at lower temps help this situation? If OP is holding down the gas (letting more air in the engine), doesn't that mean there's too much fuel? That's worked for my injectors, but they're all different.

 

I used the E85 cold start settings on his car and it helped it startup easier, but i didnt think that made sense since it was 93octane.. how can he need to crank 5-6 times when mine fires up first crank COLD on e85? the only issues I have are warm starts on E85 5-6 cranks.?

I didn't think guys with 93octane had any starting issues on the stock ecu, or are his injectors just stupid?

 

See now I thought it was warm start that screws with them? Not cold.

If this is the accepted norm, then im quite fine with it. I just wasnt sure if that was normal for these injectors?

 

It is something that doesn't jive with those injectors and evos... and it isn't everyone either... I have no problems anymore... one day the problem just vanished and hasn't reappeared...
