im going to test for codes real quick and hopefully find something usefull
will any of the c101 splice send it to limp home mode? i only hooked up the basic ones to run,(ect, fuel, o2, starter rpm to autometer tach, vss to back of clustor) i think thats it but im probly forgeting one
does the tach signal need to go to the ecu somewere or does it not matter if i wire it straight to a tach from the x20 connector?

[dranttna]

wait what???!! how do you not have a IAC valve?

its blocked off and the icv is sittin on my tool bench

[5KWattson]

yea man you need to hook up all the needed ones for it to talk back an forth i believe that will send it to limp home as well...dont quote me though lol...well how did you make your jumper harness? i fallowed the agk site

[dranttna]

i first made a chart off akg but my car it production date 3/86 so alot of thoughs didnt match up. i made a couple pinout sheets from wedophones and no-data. ill go see what pinns i actually have connected

[5KWattson]

ahhh FYL yea you are guna have some issues than...im not sure what you need to do than but there is some things you will need to figured out, mine is a 89 so it was damn near color matching

[dranttna]

yeah i know right... does anyone know of an accurat pin out for the early round plugs? half the agk chart i didnt even have a pin in that spot.

[dranttna]

i read somewere of a similar problem that was solved by isolating the o2 heater relay but couldnt find it in a search. does anyone know what this is about, or how to do it? i guess the heater would be robbing power from the fuel pump... or maybe sending false o2 signals?

[matt]

what is your idle speed? kinda high or is it normal? usually limp home mode will raise the idle i believe, you can force retrieve the codes by connecting two pins on the Dlc but i dont know which pins

No you can't....

Stomp test or get a peake.

[5KWattson]

i havent had to pull codes out of mine before so i didnt know what method to use

[e30s52]

/\ its the same as a e36 you just need power to pin 19 I think. Don't quote me on that one. If you search you can find the answer.

[dranttna]

well i connected all the wired that could be, and put pin 13 (x20) to the fuel pump fuse. im on my way out for a test run with crossed fingers.

[dranttna]

i still couldnt find anything about isolating the o2 heater with another relay. if anyone knows y pple do this please let me know. thanks

thats what i was looking for, although it seems way to simple...

on all my diagrams and testing i found that the c101 sends 12v to the o2 relay and fuel pump relay seperatly (pin 6- o2) (pin 13- fp).
im going to assume this is incorrect since nobody wires the two seperatly to the relay control ternimals.

i did the jump to fuse 11 and put some good gas in and took it for a spin around the block, althought not pushing it up to 5k it didnt seem as jerky so if its not actually fixed i will try what i stated in the above and see how that works out. please give me some input on that idea i dont want to fry anything, thanks

[dranttna]

well its still doing the same thing, just looses all power and backfires at 4,000.
i took it to school today and put it on the 5-gas analyser and got these readings

idle
hc-297
co-1.60
o2-0.64
co2-14.29
nox-78
afr-15.07

at 2,500 rpm
hc-208
co-0.51
o2-0.59
co2-14.32
nox-83
afr-14.96
from the looks of this i should pass emissions depending on who drives it but i still really need to firgure out whats going on with the engine. does anyone have an idea?
