Hi all. I just finished installing an MS2 v3.57 from Godzilla Raceworks and will be installing the Delta reground cam tonight. I'm hoping once I get the wipe patterns correct and get it all back together, I can get it up and running to about 2k rpm as quickly as possible to properly break in the cam/mate the rockers. The motor is in solid condition and ran well before I started the MS install, other than being pig rich and dangerously lean with the stock ECU. I'm hoping someone could take a look at my config and the AFR, VE and Ignition tables I've added to the base tune GR sent to make sure I'm in the ballpark. I left all of the other GR base settings alone, just these 3 tables seemed to be set way rich and very conservative, which I'm sure is the safest option on their behalf. Any and all suggestions are more than welcome. MS is all new to me so please no flames! ha.

Found a few more issues: The EDIS module had an intermittent ground on pin 9, and working backward I found a cruddy solder joint where I was experimenting with a diode. My PIP/SAW shield was grounded at MS and combined with the VR shield at EDIS pin 7, creating a ground loop. My PIP/SAW shield was combined to another ground where I connected the MS harness to the EDIS harness, ground loop #4. With all of that cleaned up I still had RPM spikes. I enabled Noise Filtering and that seems to have fixed it, but I'm not really happy with masking a noise issue. I'll try to scope the VR and PIP signals at some point, and see about adding a condenser to the coil + just in case.

Sorry, those table images came out real small. Hopefully these are better...
