also the Bosch 044 pump did NOT come stock on a VW...

Please enlighten us to what is stock on a CIS vw then?

The ones I have taken off magically seem to support 700hp...

thats not what this post is about. but it is not the same pump. not saying it wont make magic 700hp numbers, but thats not the part number or same pump. i have used one and have not doubts it is capable of shitloads of power...

Once I can swith it out of Paint Mode tomorrow afternoon, I'll be getting this shit all situated for Saturday. I'll let you know what kind of times I can crack off this time.

I was having issues about a month ago. I only run my high boost tune for the track, otherwise, its on the WG spring for daily duty. When I went to put in the high boost tune from June, it was breaking up and bucking. But mine was more so bucking all over the place.

We ended up just adding 10% everywhere but idle, and it cleaned the fuck up, and was scootin again. Conclusion/theory we came to, was the winter mixture. With cold starts being difficult on ethanol, they change the mixture to 70% during winter, rather than 85%. We automatically thought that the extra gasoline would, at worst, just make the car run pig rich, since gasoline is more efficient. Now were thinking I might have been running out of octane, causing it to detonate.

I cant say for sure, but mine ran a LOT cleaner. So maybe its worth a shot?

I DO need to talk to the gas station on what/when the changes happen. Good reminder, however the car has been doing this up top since I got it out.

Well, I took it out, and just like the external coil it seems to be running stronger up top, but still breaking up. My rev limiter is also much more defined now. The limiter sounds like anti-lag.

I think I may focus on the fuel side of things. I've been told that I'm about at the end with 1 walbro, 1000cc, E85, and 402hp. An inline helper is what was suggested, I've just got to locate one and strap that on. It can't hurt, and it can't cost that much either. (I hope)

What does your air fuel look like when it breaks up? Timing? Have any datalogs?

Any leet tunar boi would know that it looks like ass, since its a misfire, and will probably not tell you anything. Dumbshit. Why even ask this question? You think its gonna make you look smarter to appear to post tech?

An intelligent person would have asked for datalogs, to look at the air/fuel BEFORE the breakup.

can you get a secondary ignition graph?
it would let you know if it was a lean breakup.

it would tell you if the coil was doing enuff

it would tell you if it was firing at the wrong time

I've been pretty busy with work and shit, so I haven't done the pump wiring/etc. but I HAVE been driving it just every minute I get a chance. Little bursts in gears is more my style. I can lay off the freeway blasts for the most part.

Once I get the wiring done I'll update this.

You check the fuel filter??

Steve, I've been ignoring this thread for some time. I decided this evening to read it, and let you know it's turned out exactly how I thought it would - worst thread ever, short of that one in the moderator forum.

not sure if you checked it.............. fucking do it bitch. crank that shit up

more fire = moar better

trevor72 · « **Reply #47 on:** October 16, 2009, 12:18:16 PM »

excuse my ignorance, but how do you increase spark dwell time?

Joseph Davis · « **Reply #48 on:** October 16, 2009, 12:36:27 PM »

There are tables to do so in eCtune, possibly Neptune, and 98% of standalones.

You don't crank dwell blindly. The coil has to have time to charge, discharge, and rest. It's something best done with a scope, but I've had good results out of Supras w/ AEMs by taking out dwell until the misfiring goes away. I've had some borderline misfires clean up by fiddling dwell, but it doesn't introduce any extra power into the coil.

this thread wreaks of scrot

Zeniceguycrx · « **Reply #50 on:** October 16, 2009, 06:32:11 PM »

to increase or decrease dwell would be to adjust the voltage/amps into the coil?
A coil shold need a certain amount of time to charge up (dwell time)
I cant see how the ecu would effect this?

seems you are dodging the cure for your breakup.
try using a ignition amplifier... msd digital, we were trying tune my friend's last month on e85 for 20 psi single cam 50 trim turbo, it keep breaking up around 6500 rpm, we messed with the plug gap no fix,put some ngk 9 plugs in no fix. since I and my other friend both use msd with no issues we suggest trying one I so happen to have an extra msd box (the analog sci) we wired it up and bam out break up problem was gone.
