This past weekend I tried starting my car for the first time on the maftpro/speed density setup. It sputtered a little, after that, it would just crank and crank... After thinking for a while, I remembered that I didn't adjust the mainscale to compensate for the 550s I have in it...So I pulled the #6 plug out and it had a strong smell of gas. So since then I changed my oil, and replaced the spark plugs. Before I try to do this again, Can you guys look over my settings and let me know if anything completely wrong jumps out at you. remember, I haven't started doing any tuning yet, right now I just want the car to start. Timing monitor is not yet set up.

thanks everyone!

Alright so it started, yay! No check engine light, When the throttle is pressed, it'll rev up slightly, then die, or almost die... any ideas on that?

Thanks.

Sounds like what mine did. I had a bad Vacuum line source connected to the map sensor. Once I pluged in a viable source all is cherry.
Click to expand...
I unplugged the vacuum line from the cruise control and plugged it into the map sensor... that should be fine, post-throttle plate, no check valves... hmm....

I'm looking through the settings, and it looks like the setting for TPS Enrichment (Amount of fuel delivery added when the throttle is opened). current setting is 0.50. Or MAP enrichment (amount of fuel added when the manifold pressure is rising). current setting is 0.40. I'll try it again tomorrow, see if it goes way rich or lean by looking at the wideband. But overall this system is really nice, I like it way more than the lex/550/safcII combo.

cold idle is about 38-map and i think 55-VE. ....Where's the dr when you need him. It just seems like it falls on it's face when you let the throttle out...
