EDIT:

Figured out the low vac reading, crimped line I think. No longer running rich after that problem, however, at time Megasquirt is reading really high KPa readings...like, above 100...at idle, N/A.


Any way to calibrate the MAP sensor I'm not aware of?

Did you check the intake manifold front to back, side to side? There are a couple on the intake manifold that are hard to spot.

Did you check all of you IC pipes for a sloppy coupler?

was your cas set to 10* when running on the stock ECU?

what is your trigger angle in MS?

do you have a trigger angle addition set?

are you running off the timing map or do you have it set to a constant 10*?

If there isn't a vacuum leak then next thing would be fuel or spark. I'd suggest setting your spark angle in MS to a constant 10* and slowly rotate the CAS until you get the best idle. Then tweak the fuel. Then tweak the CAS. It took me a little while to get a good idle also.

Get starter fluid or carb cleaner and spray it on your vacuum connections. If there is a leak, it will suck the fluid in and the car will idle up. My aem reads no richer than 10. 10afr will foul some plugs pretty quick at idle.
If any of the connections are slightly questionable put a zip tye on them and pull it tight.

Is your aem correlating with the ms on megatune?
Make sure your aem ground is grounded at the back of the head with the ecu, That gave me problems on mine.

I had to lean my base map idle aswell as richen my cruise. Good Luck.

I'm only running a piece of the piping right at the throttle body where the IAT hooks up.

Tried to check all the connections, they seem fine. I'll check underneath.

The AEM is grounded to the ground wire on the engine ECU harness. Not reading at all in MT.

IDK, I didn't check. Should I try to do that instead?

what is your trigger angle in MS?

61

do you have a trigger angle addition set?

Pretty sure it is adding in I haven't touched it from the base map, set to +22.5

are you running off the timing map or do you have it set to a constant 10*?

It will do this on both, having a hard *** time trying to set base timing, I know it is with a degree or two, but it jumps back/forth when the timing light is set -/+ 1 degree.




Here is another odd point, MS is reading a HIGH KPa...as in around 2k RPMs it read as high as 125.....the car is N/A...I thought it should not exceed 100.

I have the MAP/Boost line hooked up to the FPR line...yes/no/maybe?

Alright, swapped back to stock ECU.

AFRs are 12.7 at idle and 10* before top dead center.

So it is something is MS, gotta figure this out.
