chipped" '87 5ktqa

Ben (and others):

I also have a "chipped" 5ktqa. I've always assumed it's
the resistor/diode upgrade, so keep the adjustable
wastegate close to stock settings, hoping that keeps my
schrapnel-potential lower. How does one find out for
sure? My boost reads higher than the 1.4bar mentioned
when the schrapnel-knob is cranked higher, I've seen as
high as 1.7, but never kept it there for fear of
meltdown. You mention opening up the ecu, would it be
obvious? I assume a real chip would have the name of the
company on it, would the resistor/diode be obvious as
well?

John,

Sounds like you have the "resistor" mod being used in conjunction with some
means of obtaining the boost, like schrapnel knob or heavier wastegate
spring.  See: http://www.homestead.com/ben_swann/boostin.html for details
on this.

I have long since downplayed it's use in lieu of the economical QLCC chip,
which provides a greater margin of safety and is a real chip.

The only real way to be sure is to open the ECU up and see what's inside.

On the note about the purchase, if the car is doing fine, then it's a
keeper.  I have done a lot with my '87 avant, and the TCO is still under
$8k in over 4 years including purchase price.
