Nood needs help with megasquirt
 
So I just dropped in my new motor with 84mm pistons, 99 head, 94 block, ati damper, 36-2 trigger wheel, ls2 truck coils, aem xseries wideband, and megasquirt pnp2. everything was going great until I got to the tunning part, I have no idea how to do any of it, I've been watching hours of videos from car passion, DIY autotune, and other megasquirt users, but I just cant seem to get the car started can anyone please help me out? Or does anyone know a reliable person(s) in Las Vegas that can help me?

ok so i figured out how to data log and here is my tune

DBZMiata 09-09-2019 03:03 PM

Do I need to post anymore information to help

SpartanSV 09-09-2019 03:19 PM

The log shows no rpm. The megasquirt doesn't know the engine is turning.

A composite log would probably be the next step.

DBZMiata 09-09-2019 06:02 PM

How would I go about doing a composite log?

finally got a composite log

DBZMiata 09-13-2019 08:45 AM

Theres no fuel on my spark plugs, but my pump is priming and my injectors are firing, anyone know how to fix this problem?

Could not see anything in your composite log file except a title.

FPR?, as in no fuel pressure? Don't really know, just don't want you to feel too alone.

EDIT: Try again on composite log. No Sync would still mean no fuel.

Also, I don't know what it means to use 99 head but not the 99 CAS. Many others should, however.

I was wondering about that also. Are you running a 99 head w/ a NA VC and a CAS off the back of the cam? I'm so confused...

DBZMiata 09-13-2019 03:28 PM

I have a 99 head with a 97 valve cover and 97 cas. When I get home from work I'm gonna try the composite again.

DBZMiata 09-13-2019 06:33 PM

I'm not getting anything out of my composite logs is this because of my cas

DNMakinson 09-13-2019 08:15 PM

If you don't have someone knowledgeable about such things come by, try looking at VVT swap into NA thread The parts about ignition will correspond to your situation.

DBZMiata 09-13-2019 08:53 PM

I will check that out thank you so much

DBZMiata 09-13-2019 11:34 PM

Ok I looked at the other thread and also references korkys book on how to do the 99-00 head swap and everything seems to be ok on my end as far as those sources of information go.
