Im running the TD04-15G kit on my 1997 Civic EX with the OBD2-OBD1 conversion. The car runs strong as hell but im having 2 problems. For some reason the ECU could not find a confortable idle speed. IT just keeps climing and dropping (900-1300)and so on until it drop to like 300 rpms. Thats problem 1. Problem 2 is the CEL just came on but i reset it without checking the code. It DID go into limp mode which blows but what do you think could have caused the CEL and the irratic idle? Here's my setup:

1997 Civic EX
OBD2-OBD1 Conversion
P28 Del Sol ECU
Greddy TD04-15G Kit
Custom Intercooler 30 X 5 X 2
B&M Adjustable Pressure Reg set at 40psi
Vortech FMU 12:1 (i know what your thinking but its just to hold me over until hondata)
Venom 255lph fuel pump
Eclipse 1st gen crused BOV
Random Tech cat
Tanabe Racing Medallion Exhaust cat back
Missing Link Boost Bypass

Any information would be great and ill post again if i get the CEL (ill tell you the code)

 

bad/inaccurate missing link setup? if it sees boost it will go into limp mode, not sure about the idle problem though.
