With this tune once the car is warm unplug the iac valve and set the base idle as low as you can without the car stalling. i want to see if unplugging the iac stops the surging.
Ok, this is with the IAC unplugged.With this tune once the car is warm unplug the iac valve and set the base idle as low as you can without the car stalling. i want to see if unplugging the iac stops the surging.
ok here is a tune for you. I think we may have to do a live tune if this does not help, if you experience heavy surging unplug the iac valve again.... then pm me and i will shoot you my phone number.
That looks much better! what do you think?See what you think.

Well.... that's because we tuned the lope out.... do you want the choppy idle back?I think I sucked in to many fumes today. Lol it surges a little upon startup and clears up in one or two minutes. Sounds pretty good. Doesn't seem to have that cam loping sound that it did previously though.. just let me know when you think it's Road worth Worthy.
Rough is a bit of an understatement.
lol it was in the "ballpark" i never saw it stall so thats a bonus. this copy should be much closer to something useable. Now the fun starts, getting the idle strategy set so that the car doesnt stall coming to a stop and working thru the bucking issues.
Good to hear, this is my favorite part....... i need you to try some short wot pulls in first or second gear. How much boost are you expecting????? i saw almost 3psi in the last log. I richened this area up to prevent lean detonation, but as always keep an eye on the WB just in case.A lot better! Thanks. Very much more driveable. I tried to get it to idle better without the surging when the car is not quite up to warm operating temperature. Looks like something that I will have to keep playing with.

Also once we get a bit closer to done with the tune i will want you to do a warmup enrichment autotune, i can do it manually but the auto tune is so much faster.
another run please, it looks like the idle has gotten worse?Let's say more 7 to 8 psi of boost for now. being gentle. The boost is set up to be on the high-end rpm. I think around 5000 rpm.

Ok give me a bit I need to look into something. In the meantime I need you to source a small fuel filter that will fit in the vacuum line going into the megasquirt. Place the filter about 6 to 12 inches before the map sensor, this will act like a signal buffer.It wants to stall out in idle now. Still surging.
I am

Awesome please try idling the car for a bit and log the run I want to see if it helps with the map signalOk uel
okay fuel filter is installed about 12in before the map sensor.
