I INSTALLED NEW 42LB DELPHI INJECTORS & HAD JIM TESTA BURN ME A CHIP TO MATCH MY COMBO ABOUT 2000 MILES AGO. THE CAR RUNS SMOOTH & STRONG W/19LBS BOOST. AT ABOUT 80MPH THE POWER DROPS OFF & MY O2 READINGS GO INTO THE .900mV RANGE {RICH}, BLM AT 132, 1-3 KNOCK COUNTS, "O" DEGREES RETARD. I'VE RE-SET MY TPS TO SPEC., IDLE AT 600RPM. THE IAC COUNT ARE STRANGE AS THEY ARE AROUND 170. AT IDLE BUT GO DOWN TO THE 50-80 RANGE AT WOT. THE SCANNER I USE IS NOT FOR TR. ONLY SO I CAN'T LOG A RUN, I JUST GET HIGHEST AVERAGE READING. I HAVE AN ANS CONTROLLER SO I'VE TRIED RAISING THE BOOST BUT IT STILL IS GETTING "RICH' FLAGS. COULD MY CHIP NEED A LITTLE RE-WORKING?? ANY SUGGESTIONS?? THANKS FOR YOUR HELP.
yeah - sounds like you might need a little fuel taken out at higher rpm's or your boost scalar drops back which will richen you out. It's more of a safety-thing. Could be your MAF acting up too, but it's probably in the chip. It's pretty hard to nail down sending a chip to someone since everyone's car acts differently. Is it acting up just now, or has it always since you got the chip?
I'M USING A "237" STYLE FPR., AT IDLE W/VAC ON THE FP. IS 36-38 LBS, AT WOT IT'S A STEADY 60 PSI. THE LOW END POWER HAS BEEN GOOD W/THIS CHIP BUT THE TOPS NOT BEEN THERE LIKE I WAS EXPECTING. MY OLD CHIP/INJECTORS SET UP WAS JUST THE OPPOSITE, LOW END SUCKED & TOP END PULLED LIKE A FREIGHT TRAIN. AN ADJUSTABLE FPR. IS NEXT ON THE LIST TO GET--THANKS FOR YOUR HELP.
I THINK I NEED NEW VALVE SPRINGS, I,M INSTALLING LT1 STYLE SO I HOPE THIS TAKES CARE OF MY PROBLEMS.
