Okay, loaded my latest msq into megatune. How do I find out what timing map I run?

Odds are you're running the same map Paul is running, so it should be fine. But, I'll try this anyways. (I'm MS2E so my megatune is wayyyy different, so bear with me).

Go to the top and their are columns. Probably the second from the left, pick it, and look and see if you see "ignition table 1" or anything like that. Once you find it take a screen shot and post it up.

No way would I load my timing map on Evan's MSM with his smaller turbo and smaller intercooler resulting in much higher IATs.

FWIW, isn't the timing map ignored during cranking? I mean not even ignored, the engine doesn't even spin at that minimum of 500rpms. Maybe the cranking advance angle is what would be the cause. On Evan's car it's set to 12.

Hiya, P. .... so when we install the bigger IC, do we have to change a bunch of settings?

i found a low of 9 F in NYC which is pretty close. I bet you probably didn't start your 23k mile 97 that day.

Yeap, you're right. Pretty sure anyways. I run MS2E w/ EDIS4 so mine it cranks at 10* BTDC whether I like it or not, and after 300 it goes to whatever MS says. I'd imagine on MS it does something similar.

Damn that map looks more retarded than Haverty. Anyways, it's not your problem. And yeah if you have high IAT's then that's the safe way to go.

I believe that's actually the DIYAutotune base map for 94/95. I know it's said to be conservative and that was the reason for running it, especially on an msm motor which has slightly higher compression than the 94/95. I don't mind getting aggressive on my motor or another motor I can afford to replace(bryan's, artie's, jes's All 90-97) but I don't need that headache.

+1. When I first decided to 'squirt, I told Paul that my goal was good power and maximum reliability/safety. I'd rather give up a few HP and not risk blowing up stuff.

I tried Sam's numbers and, sure enough, my car started much better in the cold weather last week. But this week, it wouldn't start in the warm weather. Paul suggested that (duh to me) I use a hybrid of Sam's settings for 40 and below and my old settings for 60 and above. So I made that change. But it hasn't been cold enough since then to test it.

I don't have mine solved yet. Warm and hot start is excelent. Cold start almost always required a 2nd attempt, as shown here:


You can hear me starting the car, then it catches and dies (runs around 500rpm). If I don't kill it, it will sputter a little more around 500rpm. The second try catches and runs fine. I've played around with my PWs, but it does not really seem to do alot.

Am I lean or cold or is it my ASE or WE?

something like that, the car is cranking and starting, but dying during ASE.

Try a different MAP value before decay. I have to use 50kPa over the default 80kPa the PNP map uses, else my car runs like **** after starting; hot or cold.

Richened my ASE's and I've been starting fine now in cold weather. Will keep fine tuning, but it now runs on first try.
