I replaced the injectors and sent the other ones for cleaning. Transmission oil cooler line was installed as fuel line without my knowledge. I'd love to build a few maps and just flash one each morning(or night right now.damn work) and see how it goes. I know it's cranking pig rich, I just don't have time to play with it right now. It only cranked maybe 5 times, which is fantastic for lately. Do you have a link? Or can you shoot them in an email if not? I've always let the key sit at on first, but this morning on the way home from work I just cranked it, and it started right up, with only a little throttle play. Also, at your CL Target ECT table if you don't mind. A Walbro 255 can only flow around 210 L/hr into typical WOT pressure, which can support ~850 cc/min injectors and that's about it. It's easy to find flow charts for the various pumps out there. So if you had 1000cc injectors and were running 23 psi manifold pressure, you should have a fuel pump that can flow at least 1000*4*60/1000 = 240 L/hr at 66 psi.

You should have a fuel pump setup that can flow at least that much at 43+target boost if you want to be able to support your injectors at full flow. That's the total fuel requirements at full flow in cc/min, multiply by 60/1000 to convert to L/hr. To do the simplest calculation, take your injector size, multiply by 4 for all of your injectors. Walbro 255lph will only get you to high 300s at the wheels on e85. What fuel pump are you running? I maxed a 255 lph out at 23 psi so I'm stuck with my tune atm, can't raise boost until I sort my fp issues.Īll hoses should be teflon lined. What clogged your other injectors btw? Anything I should lookout for as far as fuel lines not being compatable. 50* is about the coldest I've seen this week. I live in Alabama so it hasn't been cold here. I don't have any trouble with hunting idle at all, just the startup cranking. But, if I just put the key in and immediately turn it over without the pump primed that it will fire right up. I also noticed that if I turn the key and let the pump prime before cranking that it will have to turn over for a bit before firing. I now have it at around 13.5 for the first few seconds after it fires, then afr will target 14 for until temp rises to around 130. I changed the cl target comp ect to remove fuel. It was really rich, afr's were in the 11's. It turned over a few times before it fired. I havnt had any starting issues except for the first cold start. I myself just switched to E85 over the past weekend. You are welcome to try my tables although they might not work with your setup. He never has starting issues but he also has tgv's. The guy lives near boise so it gets fairly cold there. I have an E85 rom for a 2010 wrx posted with dw 1000cc injectors.

I want to understand how the warmup tables work a little better. Once it finally starts, it stinks of raw fuel for a second, then it hunts from 2000 rpm to ~400 rpm and back and forth for about a minute and a half.įor the time being I have raised the decay delay quite a bit to let it sit in OL warmup longer. Now I crank while pumping the gas pedal a bit, but never enough to initiate any percentage of injector cut-off. I run ID 1000's and they are brand new(old ones clogged up, didn't want to wait for cleaning).ĭoes anyone have any tables they would like to share with similar mods? I am almost certain it was the TGV's that kept it starting so well in the past. Things that were changed that affect fueling: AP rails, lines and distro block, E85 compliant return line and in tank lines, TGV deletes, hard inlet, intake(73ish mm I think? It's P&L's thing). It all started when I installed some new parts, though I don't think they are the issue as the car runs fine once it's warm. I've added fuel, taken away fuel, and tried to smooth out the after start warm-up tables(though admittedly, I don't quite understand how that logic works). I've never had issues in the past, always started right up even in the dead of winter. It has been chilly, but not below freezing. I've been struggling with cold start and warm-up lately. It would be nice if I could get it right on my personal vehicle I do run E85 year round, so I understand in the cold, things might not go quite as easy. They are difficult to tune on others cars, because if you're lucky, you get one shot. I'd like to get some ideas and maybe spark a discussion on these things. I know there are a few threads out there, but nothing incredibly helpful unfortunately.
