Nah I live in a regional area and there happen to be a couple of farms only a couple of hours away that grow specifically for E85 processing so we have an abundance of it here anyway.
So I can get plenty of fresh produce but can't get my car tuned lol
Will contact one of the guys on here regarding tuning though rather than trying to get it to the city.

did you ever figure it out? Yeah cams will lean heck out of the car since intake valve is opening up earlier and not enough fuel is in the cylinder when the injectors open. I can't help but think the car has been tuned before on SD? I mean thats so weird if you unplug it it needs to die lol. But the guys might be right about the limp home mode thing. anyway. let us know bro. gl

This has now become a fun little learning exercise, I threw the other injectors in and scaled them as per some info I found on an injector mega thread here.
I have also started to play around with the one-off IPW before it cranks and the IPW while it cranks and I am now on the right track I think as it nearly started last night before I ran out of time. I am going to play around with it a bit more after work today and see if I can't get the right settings sorted but I am confident it is a fuel thing now.
Realistically I am going to have to let someone with a better mind than mine tune it eventually but I would be pretty stoked if I could dial it in enough to get it running and driving at least.

I've also noticed my ABS light is flashing now after the ROM change but I'll worry about that later. Now that I've played around with it a bit and am starting to get comfortable I might check out "How to tune" threads and see what I turn up.

Thanks for the encouragement guys I've been following Merlins guide and changed over to Tephra rom, I also changed a few idle control and IPW settings to suit my setup and I've managed to get it to fire, it proceeds to die instantly though but baby steps huh, I logged a few things and got a stupidly high knock count at around 500rpm, I can't help but think it's firing, knocking and retarding the timing then proceeding to die.

Yeah that's where I'm at right now, it has been fun learning how to play around with it etc but the weather is starting to change and really the best time of year to be driving where I am so I don't think I wanna spend another 2 months playing around with it

Update: So Jay from Boosted Tuning ended up setting me up with a run-in tune for my clutch and we spent hours trying to get it going, he says it should have started with my stock maps because they were pretty rich. It turned out I wasn't getting enough pressure at the rail, this was caused by the the fuel pump not making a good enough seal in the pump housing, apparently this can happen when modding the 450lph pump and housing to fit, switched it back to the 255 and boom, fired right up. So yeah, fuel pressure leak in the end. It now runs and drives, Jay believes there might be another air leak somewhere so I'm going to check that out this week but my major drama is solved.
