Project 3400 Roller Cam Block (Page 13/82)

Axle and bearing replaced. Shaved Knuckle/spindle down 1/3" and added .4" spacer so rim doesn't rub spindle.
mtownfiero who did my '7730 conversion helped bebug the code 21 code. Needed to reverse the wires on the TB sensor. Now to continue to plug more holes in the Trueleo intake to get the idle down to normal...

Just wanted to post so that you'd know that we're still watching and keeping our fingers crossed! You've certainly been through more trials and tribulations than most. You just keep plugging away.

thanks!

Idle is still high. The intake seems to be full of tiny holes around the welds unfortunately. Seems to idle at 1800 when warm...

Drove it 22 miles to work today.

I need to figure out how to rewire a Fiero ALDL going to a 9-pin serial port to this ECM so I can log some data using TunerPro RT.

If you figure this out or find a diagram please post it or email it to me.

Just read entire thread,learned alot-thanks for the edumacation.
Hope you have better luck with it in the future.

There is a cable I found online for ODB1 that will read from the E or M port and it's up to the user to select the baud rate (160 or 8192) on the laptop.

Here's a pic: http://tunertools.com/vendo...iagnostics_page2.asp Pretend it's upside down for our cars.

I just ordered this one: http://www.aldlcable.com/sc...ls.asp?item=aldlobd1

I still have the data going to pin E so I'll just set the laptop to 8192 baud. The cable itself could care less if it's got data in M or E from what I can tell.

Lou i tried to call you back today but didnt get an answer...

anyhow i got the bare pins usb cable from aldlcable.com and after i installed the software and set the com port it worked nicely with the 7730.

I got my cable in today. Let me know when we can get together. Are you on pin E or M?

looks like the high idle problem is because of the IAC...whether it's bad or needs the wires reversed like the TPS is the next question...
hopefully, Andrew can re-pin the connector easily enough to try it out
we won't be able to data-log without a functional IAC... Maybe I should swap in the Fiero one...

I've replaced the IAC and strapped the coil pack down better so my loss of ignition issues have been reduced and my idle is back to normal.
I got the car at a mechanic checking for vacuum leaks as I'm still getting codes 33 and 15. Once those are fixed, then I can finally do some data logging to get Darth to burn me a proper chip.
mtownfiero JAN 28, 02:47 PM
Someday we should change how the coils are mounted. I dont think the spot where they are currently is strong enough or cool enough since its right above the headers to be good for the icm. Also you could try checking to see if there are still leaks in the intake using a propane torch bottle.
