i just purchased a car from a guy who is running a haltech e6x, t04 turbo, 550cc injectors ( i know... i'm looking for some bigger secondaries), fmic, 3bar map sensor, and 38mm wastegate. The first day, we checked everything, and started the car. (We were not aware of what zeroing the timing was) We used the settings the previous owner had, and got it to idle while holding in the clutch.

The next day, I started the car, and rose the injector duration to about 5.2 milliseconds and the car idled while i was not holding in the clutch. i started smelling gasoline from the tail-pipe, and i heard a very faint backfire... very faint. I let the engine stall out, and I tried starting it again. It cranked over, then heard a very loud backfire. At the time, I was only running a downpipe. It was so loud it made a couple of the car alarms on the street go off.

So what I'm wondering is... Is the car flooding? Putting in wayy too much fuel, and then won't start? Does the fuel priming map have anything to deal with how much fuel is injected during start-up?

What does the injection duration in the fuel priming map mean?

We attempted deflooding the car, and there was alot of fuel. I took off the exhaust manifold, turbo and downpipe, and there was a thick buildup of fuel. So was the backfire caused by so much fuel built up in the motor, or could i have blown my engine? I do not know what to expect while blowing an apex seal, or a motor, but it still sounds like it's giving fine compression while turning it over by a socket wrench.

I later did more extensive research and learned about zeroing timing, setting up the ignition and fuel settings, trigger angle and that kind of stuff.

How do you set up how much fuel is put in by primaries, and when the secondaries kick in? Is this where fuel map 1 and fuel map 2 are used? Just experimenting, I turned down fuel map 2 to zero to see if it would affect the injection duration under start-up. It showed .212 milliseconds. I have the injectors setup as staging.

what's reluctor gain? and the difference from trigger gain and home gain? (looking at maps from the e6k to be used on the e6x)

what should the injection duration be while trying to start the car? I'm running 550cc injectors all around, with stock coils, accel 8mm spark plug wires, and ngk plugs. I'm just trying to get a base map down so i can drive it until around 2k rpm at least.

I know this is kind of a nooby experience, but any help would be appreciated. I've been looking over maps by claudio and hitman, and looking at how things should be set in the injection, trigger, and fuel setups.

If it's easier for me to post up my maps, just let me know. I'm really tring to get the haltech down, and would really like to get it running on a basemap before bringing it to a place to get tuned, even though it probably is way safer to bring it to a tuner to get a basemap down.

If anybody has a basemap for a s5 13bt motor, t04 turbo, fmic, 550cc injectors, 38mm wastegate, stock coils with accel 8mm wires and ngk plugs, can i take a look at it?

Thanks guys.

Email me the map and I will look at it. Probably make you a new one while I'm at it.

i'll get ahold of my flashdrive and transfer the map over to this computer. then i'll send it to you asap. thanks for the help

I wonder if you got it sorted out? What was the problem... Good luck

it was some idiot mistakes on my part. didn't know if the gas gauge was working, so i didnt know how much gasoline was in the tank. i put a bunch of premix in... and it got all over the spark plugs. i found out it was the spark plugs because i put them in my daily driver, and it would not even come close to starting.

so, there was the high concentration of premix and fouled spark plugs. sad, i know.

i have that same prob. with the gas guage but yesterday i started mine up and it backfired so loud that it was like a 45 cal went off in my ear.. it was funny as hell to see the neighbors peeking out the windows

yeah my backfires were so bad it would set off a large majority of the car alarms on the street. i guess the motor spit out so much fuel that it just created a layer, and when it actually started.... just ignited the gas. a good cleaning out my exhaust manifold, turbine, and downpipe helped a lot with the backfiring after deflooding the motor.

I have a few more questions:
1. On the basemaps provided by Claudio.... are the ignition and trigger setups complete and will work automatically? the reason i ask, is because i read of different values for the internal reluctors and such. (e6x)

I haven't been working on my project too much due to school, so sorry if it seems like I'm not getting anything done.

2. So to zero the timing, you pretty much zero the CAS and hit lock timing at -5. Then just start the car?

3. And for the tooth offset, why does hitman recommend 3 or 11? I set mine to 11, but will it not fire enough?

4. and im pretty sure on this last one, but if I'm running 2 low impedence 1600cc injectors, I just change the amperage from 4v to 8v for those two injectors correct?

thanks guys for the help
