We are trying to get this thing figured out. Has anyone else here top swapped a 2000 Monte?

2000 Monte Carlo SS Top Swap Commanded AFR Issue - HP Tuners Bulletin Board

 

I swapped my top

Have you replaced the o2 yet to see if that has any effect?

 

What are the physical symptoms of the car?

I'm with 01 Monte SS replace the O2 sensor. If you haven't done it in a while, I'd start there also. Did you tune your PCM is from a vendor?

 

Did you switch to the 2-bar Map yet?

 

I'm not an expert at scans but it looks like you are getting 6* of KR. Wouldn't that cause some issues?

It also looks like open loop has a afr adder causing the 15-16 afr before PE is enabled. Anyone else seeing that?

 

I'm .gonna check over the o2, it has a 2 bar map and the physical issue is the afr spiking. It leans out in one or two places causing a missifire at wot. You can see how it is 10.2 and then spikes to 14+ while I'm wot.

Tje knock will be figured out after this. I'm running 89 for the time being.

 

Just pull the blower belt off and run 87

 

Wideband tune at WOT. You can't narrowband tune that thing

 

What file are you using? If you are using a N/A 2000 Monte Carlo file, you have to physically change some stuff in the file on Tiny Tuner for the 2 bar MAP.

There is a MAP look-up for NA and for Supercharged cars. If you don't change it, it will not work correctly.

I have a copy of a hybrid file that some of the people with Monte top swaps have been using including myself. It's basically a 2002 Monte Carlo file with the supercharged settings hex edited over to the file.

 

We changed over a lot of info from a gtp, pretty much anything that was different got changed. My friend who did it knows most of the technicalities. If you could send me that file somehow that would be awesome.
