Supercharged 2010 Camaro SS with NA tune?

[CBC]

I'm brand new to HPT so bear with me please. I purchased HPT for my sons 2010 Camaro SS. It has 37K miles on it and was 95% built in 2010-2012 by Thunder Racing (Baton Rouge LA) who is now closed. The car had been sitting in his garage since 2014 when my son bought it Jan 2023. All modifications were done by the previous "original owner". He told us that the car had a very reserve tune in it to get it running and needed to be tuned. All we have done to the car to get it running is change the oil, put in a new set of plugs, and replace the (original) battery. That's all it needed to get it running and he has been driving it as is since Jan 23. The car cranks, idles, and runs great although it is real rich at cold startup. He daily drives it to work sometimes and has drove the car several hundred miles in one day with no issues except for being rich at cold startup. We just recently installed an AEM wide band, AEM boost guage, and a line lock. For the first time, we took the car to the track and made several 1/4 mile passes with it last weekend. I was able to log the passes with HPT. (I haven't figured out how to get boost gauge tied into ECM yet so wasn't able to log boost) The car made some good straight decent passes with a best of 11.30 @ 123 with a 1.57 60'. It took us a while to figure out we had the shift at 6000 to stay of the limiter. Also seemed to stall after the 1st to 2nd shift like it was hitting some kind of limiter then it would pick back up ???? We made some passes leaving in 2nd gear and some leaving in 1st. Ended up breaking the rear end after the sun went down and the track got tight. After looking at the data from the passes and looking over the OG tune, I'm thinking the car has a NA tune in it. Like I said, Im brand new to HPT and this type of stuff. I just wanted someone who knows what they're looking at to take a look.

The original owner gave us a folder with receipts from the mods done to it. This is what I know about the car:

It has been "tuned" for the supercharger. I use that term very loosely. It does need a lot of work.

First thing is get a red label map sensor for it. GM PN 12592525. That way the PCM and you know how much boost it's making.

Second thing is, you'll need to do some fuel system upgrades. The way the PE is setup I'm pretty sure it's dropping pressure up top.

Then you need to get with someone who's done a bunch of these. There are a few of us on here.

Thanks for your reply. I noticed on the pass logs when the MAP hit 120 it started pulling timing and seemed to add fuel for a moment. I guess its confusing the PCM with the MAP maxed out ? I also noticed in the general tab under engine it doesn't have the correct cylinder volume, still showing to be 376 not 416. I would assume that would matter on that big of a difference. It puzzles me that the supercharger is "not fitted". Like I say, I'm very new to this and may not understand some of the terms. Thanks for the help, I will get a MAP sensor for it for starts.

The supercharger fitted tab should not be changed even with a supercharger. It creates a hiccup like bug in GEN 4

Thank you, that was one of the reasons I thought it could be a NA tune.

The MAP hits 120 and just sits there because that's the upper limit the stock sensor can read. It's actually beyond 120 Kpa.

Can you elaborate on this please? Are you saying for any Gen4 ECM (N/A or Supercharged) to leave all OEM values alone? What kind of bug do you see? Is it the fuel spike like when you fail the MAF?

It can cause them to idle up among some other things depending on the OS. It basically switches them to start looking at background tables on the gen 4's that aren't populated all the way to the torque model parasitic loss tables for the supercharger and then who's to say those tables are populated with anything meaningful when they are populated... It's not like the gen 5's where it just activates the ability to look at another temperature sensor.
