ECU Shoot-out?

Has there ever been any comparison between the chipped ECUs available for the '86-88 5KCSQ? How do you know which "chipper" to go with?

Antony, Search Audifans archives for "QLCC" or "Intended Acceleration" or "TAP Chip" The QLCC stands for Quattro List Chip Club - there was a chip created by some core members of Audifans and distributed widely - if you borrowed a copy of the chip you could burn your own, but I found that difficult and ended up buying a chip from Ben Swann. All that said, you might read the stuff on Boost Mods on

is something called a Resistor/Zener modification ("r/z mod")- thatfools the computer into thinking that the boost pressure is always 1.4barwhen the actual pressure is much higher in the intake manifold. Thismodification is super cheap (ie - less than 10 bucks at an electronicssupply store) but there are problems associated with continuing to supplythe engine with the fuel quantity for 1.4 bar boost (ie - running lean).The computer has an overboost protection built in and should the boostpressure be detected above this level then the computer removes the groundfrom the fuel pump relay (and your head hits the steering wheel). In oderto bypass this, some have hotwired the system by adding a static ground wireto the FPR - the computer can't shut off the pump (good thing), not evenwhen the car crashes and engine dies (ooh, bad idea - think carbecue).The best advice that Ben or Scott will give you is that you should "get itstock" - ie, get it up to spec before modifications - otherwise you won'tsee the full benefit of the mods. The price for a QLCC modification (onBen's site) is dirt cheap for a decent mod.Cheers! Steve Sears
