first time start up!

VSS has been reading great. It's a JTR one.

I re-burned the chip to a 'factory' program. Started it up, it ran and then died after around 5 minutes. I couldn't connect to the PCM with my cable at all. This all happened last night. I wasn't getting any spark while cranking.

I re-installed the factory chip and it fired right up. It runs poorly, but at least it runs.

I'm going to re-install the burned chip and re-try later on. I'm thinking I may not have gotten it seated into the G1 correctly.

Edit: I managed to connect to the PCM with Tuner Pro and took a couple logs.

When something bad like a chip not seated correctly, or backwards usually sets a Error 51. Nothing works well with Error 51 set. Clear codes.

Ok, I'll check it out when I plug the PCM back in. Thanks!

To clarify from the 1 million other posts, I need to disconnect that wire to set timing? On mine it's tan and has a connector near the PCM. Set initial to whatever my bin says it should be?

Then clear codes again cause it will set a Error 42...

Why are you running a base timing of 12? Set it to 0 and if you need more timing add to spark table. If you set distributor to 12 and put 12 in bin for base? You did nothing? Well except change injector timing...

To start, because we know the Jeep engine needs more spark and to simplify your tuning for now... leave bin at 0 and set distributor to 5. Now you added 5 across table. WOuld have to add 5 to ADX file conversion to see accurate spark advance.

Really? I have never seen this mentioned before....

Yep.

The base timing set in the bin is subtracted from the final output.

Ahhh!! Copy that!

Ok!! Running MUCH better. It idles great, especially in closed loop. How do I check/clear codes again? It's popping back thru the t-body around 1500 while trying to accelerate. Once you're up to speed, it's much better.

FYI, I haven't adjusted down my initial advance in my BIN to 0, it's still @ 12*. That's in 4133 on a 16197427.

I have always set my base timing to 10 or 12 degrees because the AMC motor idles better there. I had trouble keeping it idling at zero.

If you have my $0D ADX all you do is click Send next to the Clear Codes Macro. Right click on tool bar and choose them all, see if you have the commands.

If not disconnect power to PCM to clear codes.

If your distributor is 0 and bin is 12, then your minus 12 degrees from a stock Chevy spark advance table. If both are 12 well then your just at a stock advance table.

Popping back is normally a sign of not enough AE (Acceleration Enrichment) Carb pump shot. Increase AE TPS and AE MAP both by 50% and recheck.

But from the looks of your log your running out of fuel! High load, 1200 to 1600 RPM 70-80 MAP your hitting 156 BLM, then it goes PE and locks at 128 so you can't tell how bad it's getting.. Have to check fuel pressure and flow...

At idle your fuel pump voltage is dropping to 13.2, acceptable and normal in old vehicle conversions because of altenator. But idle is also low, like 525 so increasing idle by 100 RPM will help idle as well as opening throttle blades a little to reduce IAC count. Turn screw in 1/4 turn to lower IAC counts. RPM has to be done in bin.
