Just checked and it is batch during cranking. I am guessing it should be this way in order for this to work.

Mine ran for about 3 miles and died. Had to get my car towed back to my house. Injectors are batched during cranking. I am may have to go back to the original configuration.

Mine has been running the new configuration since i posted this thread. Which ecus and wiring harnesses do u guys have? As to why your car would run 3 miles and then stop.. that makes no sense.

You guys sure you rewired the right plug?

I have the e420c with the old harness (no idle select pinout). Yeah does not make sense either why it would just quit running after 3 miles. Maybe the new configuration only works with the new harnesses.

Yep wired the right plug. It's the only plug with 8 pins.

Wired the right plug as well. E420C with the newer harness I believe (w/ jumpers to select factory or Adaptronic for idle)

Ok, I tried it again. This time with the engine at running temps and it runs...better. The idle droop when i jab the throttle off idle is now completely gone. All downshifts are much easier to do as I used to have to really stab the throttle deep. It does take a few more cranking cycles to get running though. I'll have to try it from cold before I keep it permanently. I'm still skeptical....I've gotten used to all these issues that they became the norm.

So today with my new map it didnt start.. bumped up the cranking fuel 4 points and it started right up. So no this did not cause my bad starting issues.

It's weird as to why it would not start before but now it started and ran better.

Probably something to do with the engine not being warmed up before. Not sure how changing the injector wiring phase affects starting. I'll try starting it tomorrow after it has been sitting over night.

Try adding a bit more fuel in the cranking fuel cells (in the correct temperature). I am running VE so i added 4 and it started perfectly.

That may be the answer to my problem. I'm going to try that. Thanks for the tip.

Well i was having issues starting from a hotstart (75+ coolant temp) so thats where i bumped it up. I never had the hot start issue before i changed the injector wires.

I got a couple pointers from Andy on the Adaptronic forum and so far it's working well. It'll take at least one track day before I'm fully convinced.

amazing!

i have been chasing this throttle response issue for quite some time...

this fixed the issue about 70%. Now i am seeing more reasonable responses to my map prediction table.
