I haven't touched anything on the car yet, im going to later today, but im thinking it could be the settings on we set on the emu?

Theres your problem right there bro. The Walbro fuel pump will crank the fuel pressure to the moon! You need to either put a regulator on your fuel rail or take that walbro out (depending on where your shooting for hp) I just had the same problem!

im shooting for 350whp, but fuel pump shouldn't affect the ignition. I drove fine for like 2 weeks with my walbro in.

sIIooo

Can you have the walbro without a fpr if you have bigger injectors. I thought the stock frp could handle a bigger fuel pump.

well it sounds like it got progressively worse because your plugs got fouled. If you want to start the car again, get new plugs, but in regards to your setup, the car is clearly running rich. Do you have a A/F gauge? are you sure those are the only settings you enabled on your setup? check connections to map etc... and your grounds!

yes Walbro +larger injectors + stock or AEM FPR will work fine (assumes that you have a piggy back or tuning system that is able to scale the injector pulse width appropriately)

Pull a plug. I bet it's wet.

Spray them with WD40 and refit (all four). The car will start and idle as it did the first time. And then get progressively worse.

so i changed the spark plugs, and my car started and idled fine. i drove around a little but to make sure i can make it to the tuner, so as i was driving. once my car was warmed up, as i was driving as i slowed down to make a turn my car idled below 500 almost as if it was like 100rpm, so i revved my car to keep up the idle so my car wouldn't stall. im assuming this issue is because the settings were changed on the emu and need to be tuned? also as i drive maybe going around 20-25mph in 2nd gear, i push on the pedal a little bit to go, but my car starts to struggle, so i revv juts a tad higher to keep the car going and everythings fine. im assuming all this is happening because no tune, but will see better results after monday once i get tuned. :]

thanks guys for your responses.

crav3s2k you never did email me your maps...


I can send you a base map that will allow you to be able to drive the car.


Just need to know what mods have been done. Specifically if injectors have been changed there size and lag time if known.


I can get the lag time in the ball park by knowing the size and manufacture.
