its a crank no start
fuel pressure is ok with the ignition on
i do get spark
dont know the comp but im sure its good
hks 272 cams
0.91 a/r
the problem is i dont know exaclty what im doing with the software i dont know how to get it to idle (i do but i think im missing something) i cant get the injector response time right nor can i seem to get the right afr to keep it running if if i get it to turn on it floods and dies from running rich im hoping someone has a base file i can use to create the rest of my map
the tuning procedure is faily simple and straight forward for the aem fic but i cant seem to get it down

Question , why a piggyback .. between those 1000cc inj and fairly large cams and the fact you are using stock the ge Ecu , a good standalone would be best in any Na-t setup.. check ECU masters ...if you are interested in a very affordable setup that will run your car 20times better , I may be selling my aem v1 designed for ge motor with hks dli for exceptional deal.. been in my car over 8 years and has been flawless . Pm me for details

i bought the piggyback as an easy way to get the car running before i bought an ems 1/2 the initial tune tht was on it was veryyyy crappy it drove and i could move it to my shop and home ect but itd die after hard pulls and boost would break up after 5-7psi even though im set up for 10 and then the idle was bouncey on cold starts and it ran really really rich so i figured id try and edit the fuel trims for idle i ended up having to flash the new firmware and lost the base tune i was running
