James,
Glad to see some more N9T enthusiasm up north!
I must have missed your intro to the mailing list and quite a bit on your
car, but if it's a 1985, it's an N9T, not N9TE. Injectors are high
impedance, N9TE and EA are low impedance. ECUs are not interchangeable. What
bosch # on your ECU? Did it have a processor and an eprom, or a pair of
vertical ceramic boards hidden under 0 273 002 plastic thingies?
Anyway back to your problem, the 6 flash on the N9T and N9TE(A) can only be
one of two things. If you need to turn the car off to get rid of the
flashing, then it's the pot sensor as you mentionned. In your case it's
different, so it's the load signal from your injection box.
In this case, considering you replaced a 12MOhms by a 10MOhms, that would be
my guess. Which resistor number was it? 12MOhm is brown-red-blue. Also, is
it blue, grey, red or beige in body color? If it's blue or grey, these are
definitely precision metal film resistors, depending on the tolerance, they
range from 0.05% to 2%. Gold ring is 5%, silver ring is 10%. The smaller
reds are high precision. All others are 20% Those on risers are at the lower
end of that spectrum and are matched. 10 MOhm is way off by these standards.
I would get a 2MOhm and install the two in series. What you'd really want is
to get a 12MOhm metal film resistor.
I'd also be wary of any mylars on that signal path (capacitor, red). A few
electros, but none are on that circuit.
Ciao,
Francois

Subject: 85 Turbo Starts !! / Runs / Throws ECU codes
While waiting for Jim Lill's Injection ECU to arrive (I agree Jim -
should be here on Monday) I decided to take another look at the
injection board I have..... under really, really close inspection I
found an overheated resistor (12 megaohm) / scorched board etc...went to
the local electronics store and found a suitable replacement (10
megaohm) ..... and soldered it in.....
The car started and ran so we went for a test run...... getting it on
boost in the higher gears it accellerates fine then throws a 6 flash
code (and backs off the timing temporarily causing the car to buck and
snort a bit (this IS Calgary )).....then it runs fins again until I get
into the boost..... same thing happens in the lower gears but too fast
for me to catch the codes..... I think 6 flashes for an N9TE is either
6a connection to potentiometer from ECU bad or 6b no load signal from
injection ecu.... any thoughts / recommendations ?
Thanks
James
