165 to 730 swap a succes i think.
Well just finished repinning for my 730 ECM and the car started -
WOOO HOOOO!
I am getting a code 43 esc failure but i am guessing that is because i still have not recieved my 92 SD memcal or have i changed knock sensors yet, i would imagine one of those would deffinetely give me that code.
But i saw no other codes and long as one of those are the reason then im all good and ready to relearn how to tune.

Hi there KVU,
It did not really go half as bad as i thought it would,It took
maybe 4 hours total and that was alot of going over the same work just to be sure . but if i were you i would log what color came from where because if you are repinning then you have no way to trace your steps to see where a designated wire came from if you do happen to mess up.
Like for instance i found that i still had a wire on the old b3 connector that should have gone to a9 i think of the new connector,but when i went to move it there i had already located a wire there, but where did that one come from???
And i cant really call it a success yet until the SES light goes off
which im sure is from the v6 memcal.

87T/A,
I ran into a similar problem on my 87. When doing the conversion you can unplug the under the hood ESC module, which is great. BUT, the knock sensor signal wire from the computer and sensor itself meet at that module so by unplugging it that circuit is open. You will need to jump I think its terminals C and E? if I remember correctly. I sent Mike Davis an email about the problem I ran into and he said "oh yea.. I forgot about that
" or something to that effect and then he added it to the webpage.

I have disabled my ks by grounding the ks wire through a 3.9k resistor.That was told to me here and have no problems since.This is from the 730 swap tech article
The '730 ECM ESC circuit is looking for a 3.9K ohm resistance in the
knock sensor and the '165 KS is 100.0K ohm. You can put a resistor
(From Radio Shack, et al.) to bias the 100.0K ohm KS so that it appears
to the ECM as 3.9K ohm. The resistor should be between 3.8K and 4.2K
ohms, and connect between the Knock Sensor wire of the ECM (GF9) and
Ground.
If you are building an adaptor harness like me, you can
solder this between B7 and A12 of the adaptor plug that your
harness plugs into. (assuming you are using the jumpered ESC
connector on the firewall. If you are bringing a new wire
thru the firewall, you will have to connect it and A12 with
the resistor)
If you are using the ESC connector on the firewall to bring
the KS signal in, you will have to jumper pins "C" and "E"
on the ESC harness plug. While you are building the jumper,
you can add the resistor between the jumper and pin "D"
(making it a 3-prong jumper) and your '165 KS will be properly
biased for use in the '730 ECMck if you did all these steps.

Thanks for all the help guys ,
I changed the KS today and the Memcal w/aujp and the
ESC failure is gone
The swap is total success so far (i hope)
But now i have other problems.
i have no load value showing on my scan tool...
When configured for 165 i had a kpa value.
Now i dont and the only thing i can think of is i config. the tool
with vin # 8 (for 8th digit) and F (for fourth dig) Is that right for a
90-92 f body 5.7?
I think there is a way to calculate KPA is'nt there?
W/out that i cant start on the VE tables.

Depending on the scantool, you MAY have to change the 10th digit, too (if it takes one), which is the digit that stands for the year of the vehicle. The 8th will only tell it that it's a 350, not that it's speed-density. The 10th should distinguish that.

Hmm thats not an option on mine only 4th and 8th,
my scan tool has definetly changed ,it see things that were never there before like oil temp and others . but i cant figure out the map kpa.

Do a search with the key words "kpa volts map" and see what you see. There are a few posts with conversions. If you were to use the Moates scanner, I believe he has it in kpa.

Thanks guys,
Just prior to reading this i did so and found some conversions.
Unfortunately my autox will not read the 730 in metric units
but converting volts to KPA should be just fin just a little inconvienent.
Thanks again.

Correct,I contacted autox and they said some ecm will not allow
scan tool to read metric. Makes no sense huh,my digital dash
has both options.
Speaking of does anybody have a temp chart from metric to standard?

Celsius X 9/5+ 32= Farenheit
F- 32 X 5/9=C
And if you search around the net you'll find lots of places with cheat sheets already made up, possibly on this same site even.
