hey guys, i'm new to this forum and looking for some help. i just picked up an 87 fc3s with a 89 jdm 13bt engine in it. the problem is it is running a stock ecu and is having a lot of afr problems. i guess my question would be who makes and what the best piggyback ecu would be for this year. also looking for someone in the ct area to do the tuning. thanks for any help you all can lend.

I am using a APEXi AFC NEO piggy back fuel computer on my S5 13BT.. It is really easy to tune and easy to install!

THEY DIDN'T leave the s4 ecu still in there did they?
