ok guys heres the thing i have a 92 hatch with an 1994 LS B18b1 with a GSR tranny here is my problem it hits fuel cut when it hits 6k rpms and NO CODES, i installed a SAFC2 that i had laying arround thinking i might be able to by pass the fuel cut but it still cutting @ 6k rpms also the SAFC2 and the rpm tach are not the same they are about 2k rpms off when the tack register 4k the SAFC2 registers 3k i installed the SAFC2 correctly according to the apexi diagram please i need help!!!!!!

 

Make sure you set the number of cylinders in the SAFC to 4, I believe default is 6.

The honda tach is off in my car by about 300rpm, because my highest rpm is 8200 on the VAFC, and around 8500ish on the tach. Most honda tachs are off like this exponentially, meaning the variance grows as rpm increases.

Are you sure its fuel cut, or ignition cut?

 

the SAFC2 is set at 4cyl does the arrow in the safc2 thats next of the 4cyl should it be pointing up to the right or down? also what about the fuel cut? the problem has always happend as far as hitting fuel cut @ 6k rpm's the ecu is not chipped @ lunch ill go see what type of ecu is in it when i hit fuel cut the rpms on the SAFC2 are 4800 rpm's and the cluster are 6000rpm's shouldnt be that way huh? something is bad on this thing and its bothering the heck out of me.

 

ANYONE? what type of ECU should i get or have? would chipping it help?

 

What ecu are you running? If your tach is off it maybe cutting off at the correct rpm but your reading is off. Should be around 6800

 

with a chipped ecu what should i get if im going turbo my friend chips it with chrome for 50.00
