Found most of my problem tonite. My bad. somehow in the fueling setup it got switched to 8 cylinder for a v6. My LC-1 wideband controller is running at about 7.5-8.5 on MLV around 19 on the gauge in Tunerstudio (not moving). I will use the led to trouble shoot it in the morning. It was idling great ...

Thanks grippo. I reset the trigger offset. It appeared to be about 9 dgrees off. Pinging is gone. Did a datalog of the next drive and it ran well...except for spikes in my spark advance, fueling and in my rpm. Then started to run badly. AFR went low to 8.3, then really high. I have attached 3 logs ...

I have changed my ignition input capture setting from rising edge to falling edge due to a ms II 3.0 board mod I did to get a cleaner tach signal. Does this change my timing at all, i.e. the ignition offset? When I try to accelerate my a/f ratio goes lean, sometimes to as high as 21 and I am ...

I made some progress. The 12v switched supply only give power for about 5 seconds to prime the fuel pump. I used an alternate source to supply power during calibration of the LC-1 and it worked. What puzzles me is how things are working without the one red wire from the ignition?

Please help! I'm so close! I found one wire I missed. The red one that runs from the ignition switch to the main 12v source, just before the 20a fuse (as shown on the wiring diagram from DIY). Do I use a switched 12v source like I did for the other yellow wire coming from the ingnition switch? Doesn ...

Hello-I am finishing up my first MS II 3.0 board. I am using GM HEI with a MSD 5/Accel coil on a 4.3 v6. Is there any reason to use the high current ignition driver? Is it better? I will be switching to a Ford EDIS system later. Will this cause me any problems? Can I easily switch back to using the ...

Hi
I am assembling a MS II 3.0 and have already assembled a Jimstim. When installing jumpers, is it ok to solder jumper pins and use the actual jumper connectors with the proper terminals on each end or should I solder the wires directly to the board? Also, the jumpering is always done on the bottom ...

Interesting article, seems to have some merit. I did a compression test prior to removing the engine and it was about 180 pis all around, with a compression ratio of about 9.5 to1. There was no appreciable ridge at the top of the cylinders and I removed most of the carbon from the top edge before ...

I don't know if this is the right place for this post. Sorry if its not. I need to know if it is safe to install new rings before installing the megasquirt? If I have problems, will this cause the rings to not break in properly?

I have a 383 stroker that I bought used (for $800.00 including the ...
