Just wondering if anyone has a decent running MSQ, VE and Spark table they could send me for my megasquirt. I'm running MS2 extra on a 9a 2.0L 16v NA stock 1.8t injectors. Also if anyone has some pointers for me to follow for start up and tuning. I've got spark on all 4 Cyl 230-250 cranking RPM, TPS is working great. Tunerstudio says my req fuel is 15.8 based on 1984 cc, 210.2 cc/min inj flow and afr of 14.7 Does that seem normal?

Ok I got the base tune thanks for that one, and I've got a good understanding of how I'm setting the timing. The injector PN is 0-280-150-477 There are 2 flow rates given for them one has 20lbs, 210.2 cc the other has 22 lbs 240 cc Not sure which one I have. When I plug the numbers in it give me a req fuel of 13.8
Just really started to play with getting the engine to idle today It seems to catch, sputter for a sec and die. I may have the timing set wrong but I don't think so.
Ok I set the ignition capture to "falling egde" and then followed the directions on the mega manual for the set timing. I started the motor (kinda guessing where 6 degrees would be) cranked up and adjusted it. The dizzy now looks like its proper. My question now is as far as setting the timing should it be fixed at 6 degrees then adjusted to the 6 degree mark on the flywheel or fixed at zero and adjust to the 6 degree mark on the fly. I also should probly hook up an O2 sensor too and figuring out Data logs. fun times
So its idling (around 13-1500) a bit I'm working on bringing that down. I'm figuring out my GM IAC right now or if I can't do that then I'll try out a bosch one I guess. Anyway I've been playing with some data logging and other things and I notice that every now and then my PW drops to 0% and I don't know why. Here's a pic of the graph
And LC-1 wide band is ordered also
Wow, I didn't even notice that at all. At first glance I thought that was just 2100 which made since I revved it up a few times. Which signal lines are most important to shield from noise? Obviously RPM is one. What about O2, TPS, CLT and MAT? I did find adding a little ASE helped out starting. Looking through I also have to reconfigure my Coolant and air temp sensors. There is no way its 89 degrees in my garage. I live in WA. So time to start figuring out easytherm.
I also think I have a ground issue. If I look farther along my log, the Bat voltage drops severely on start up. Running I've got 13.2 to 14 volts. I've noticed that the main battery neg cable gets warm. Its Super old and oxidized. Again new one in hand and ready to be installed. I'll also clean up any old grounds I come across while I'm there.
So today I took care of a few issues. First was the noise problem. I put the shielding cover on the dizzy and made sure all of the hall sender wires were clear. Installed a brand new Neg battery cable. Wow it made a difference in the way it cranks thats for sure. Cranked it up played with some settings and took a log. Every now and then my Pulse width still seems to drop to Zero for no reason I can find. Its not all the time just some time. I'm still gonna shield some other wires. just to be sure its not that.
**highest rpm today was 3000
