last night i sat and thought and thought about this and decided that i don't have a leaking injector and i don't have a vacuum leak it is the megasquirt so i went in this morning and pulled it apart and cleaned it with electronics cleaner i let it dry then plugged it in and now it said i was lean once i got it to run and the blower is building boost fast i saw 15 pounds of boost it seems the belt has stopped slipping i also need to get the boost control valve working so i sent for a new actuator to repair it

I am so lost right now i have no idea why the engine wont run after it has run things i did today i check for spark on each cylinder and it has it so i did a injector test with my laptop and they fire and the circuit is fine i am going to change the oil as it smells of fuel and i am not sure if the engine has so much fuel every where it is gonna take a few days to dry out and maybe run i know it is strange to have it start and run and run good with it no pouring black smoke out of it and sounds great to where it just wont start with the same setup

well i think this dam thing washed down the cylinders and now i have low compression and that kills it starting i am seeing less than 100 psi on the compression test i am going to pour stp right in the cylinders to get a thick oil coating on the walls but i think it is toast

good news bad news ok it looks like my original Audi V8 has a bad intake valve guide or seal and that was causing all the smoke as i can see oil in #1 intake port and the exhaust port is oily where all the others are not this engine was running when i pulled it from the fiero so it should be fine the engine in the fiero is not building enough compression is my thought as i can only get about 60 pounds unless i pour oil in the cylinder and that does not last for only a few cranks then it is back to 60 so i will pull some heads and get things swapped around and it all should run again

Ok i just got done reloading the firmware on the Megasquirt just in case that was messing up i just want to make sure before pulling the engine out that it is the engine as it would really suck to swap the engine and still have it not run

I've been following this. Looks like you have a pretty cool project there. I don't know anything about MS or any SEMS, so I can't really help. Good luck.

reloading the firmware did not make it run so i will have to pull the engine as it must have either jumped timing on the cams or it washed down the cylinders and caused damage so it has low compression and since the compression comes up by putting some oil in the cylinder i think there is bad rings or cylinders

I was wondering if a 32 valve intake would fit on a 40 valve engine any one know?

Manifold? No the flanges are completely different.

well i am going to try changing ecu as i was holding the throttle to full throttle and it started firing the injectors when the time before it worked right and didn't fire them at full throttle and i have not changed a dam thing on the ecu tune as far as that is concerned so i bought this from Egypt Sptronic http://www.sptronics.com/ i bought it on ebay it is really inexpensive
