What do you guys think would cause this issue...
Cold start fires fine, hot start, ive gotta hold it WOT like I'm clearing a flood. Once it fires it blows a poof of black straight up then it's a nice clear haze.(remember, I have a hood exit so I can see into the exhaust).
Does that sound like I should turn down the pulse width at startup vs what my ECT sensor says?
Yeah, ill just bypass it tomorrow,
I also had a rubber elbow on my cold side collapsing every time I hit the throttle. I should've videoed that thing.
And is it common for air to whistle pretty loudly by the throttle blade?
What do you think about VR1 20-50 non synthetic?
So I'm at an end for the day, afrs still need work higher in the load range, but she cruises fine, idles good. And shoots flames out of the hood
I may leave it as is until I get it dyno tuned.
I think I need to change plug wires though, I'm having a slight stumble around 3-3.5k rpm.
Has new plugs, and a good distributor, and screamin demon coil. I'll do wires tomorrow sometime.
How is the weather where you are?
One minute is sunny next it's piss pouring cats and dogs, then back to hot and humid. All day for the past 4 days.
About an hour north of Nashville in Ft campbell, KY.
Even as hot as it is, when I was driving around street tuning, over a 50 mile span, it never went over 200. I'm also running a 192* thermostat. Also running VR1 20-50 since it's so hot out. I think it helps, but I really want to get a oil cooler with a thermostat to really be able to control all the fluid temps.
Would you mind posting some good timing tables that might be useful for me?
I drove the car 60 miles to get tuned, but the tuner said he wasn't comfortable tuning using the pro-m system because he has never seen/used it.
I've been doing some light street tuning and the car runs awesome for the most part, 14.2-14.7 at idle, and 14.7-15.3 at cruse and under light load. (A few long steep grades helped dial fuel in tighter.)
but I think my timing table could be improved. Around 3-3.5k I still have a little stumble but once I pass the hicup at WOT, it hunkers down and pulls hard.
I also think you were right that, a little more timing would help out at cruise I think, might make it a little snappier.
