Car runs fine in limp mode (by fine I mean limp mode fine, 2k idle 4k limit and a 15 minute plug fouling)
Car barely starts SOMETIMES and when it does it makes the entire car shake.
Anybody heard of this??

I even tried my buddy's good known working ecu... same ----

Did you try a different basemap? Try p72 code instead of p30 and see what happens.

 

good idea but the obd2a jdm ecu that came with the engine was tested on my buddy's car that gave me his p30 to test (hes got a 98 civic with an adaptor harness to run obd1) and his b16 starts up first try.

in limp mode is the map sensor monitored?

 

mmm, I don't think any of the sensors are really monitored. When I used pop into limp mode from overboosting my old z6/afc hack it would still run, but had very unresponsive throttle and ran extremely rich. Once you came to a stop the car would die until I reset the ecu. There's got to be a good reason you're starting off in limp mode to begin with.

 

I purposely started the car in limp mode.
Only way it starts with the first crank, otherwise it sounds like a 2 stroke and touching the gas kills it

 

uve got 3 more days, after that im coming over with the sledge hammer

 

The only thing I can really think of that would make it run like that is if the timing belt is off a tooth. My friend's 92 gsr acted the same way, ended up being 1 tooth off on the crank. At first it looked like it was on the mark, but when I pulled the pulley off and looked at the mark on the block it was indeed off a tooth. I know you said you checked it, but I'd check it again. I usually rotate the motor 2 times after setting a belt, just to make sure it comes back to where it's supposed to be.
