I have an old LC-1 I'm thinking of retiring. I am also thinking of running two wide bands for the narrow band simulation to eliminate the NB and use the same for wide band tuning. Can the scanner...

Different pinout. Blue/Green(P59) vs Blue/Red(P01) connectors. P01 had 512kB memory and P59 had 1MB.

Just use the P01/0411 PCM and LS1/LS6 vette type harness. Don't over think it.

I believe all Gen3 motors used the same physical PCM minus the 1998. Just the OS was different.

There is no difference between the PCM's themselves. The OS is also the same. It's just the tune that may be a tad different from year to year. P01 is the PCM model like E38 for the newer cars.

2001 or newer.

Physically that are all pretty much the same P01. The OS just needs to be a vette version

Many of the aftermarket intakes do not leave room for the factory bolts. Pan head hex bolts must be used with the FAST intakes (as an example) otherwise they leak quite badly.

Bump, I've updated my OP and title to reflect the current state of the issue I'm having. Thanks for looking!

Edit: From what I can tell the issue might be the combination of offset and inj pulse....

Min INJ PW divided by 31.124308

As an example, my Min INJ PW is 1.5ms (based on FIC inj data)

1.5/31.124308=.014

They all should be set to first error. I just changed that yesterday but it made no difference.

The log does match the tune. It was just the tune I used to do the RAF the afternoon before. All...

BLUF: I need to get my observed Min Inj PW lower. FIC lists it as 0.45ms but I can only get down to 1.7ms.

After I installed the FIC (clinic) 525cc injectors I've been having issues with hitting a...

Firing order!!! Then injector data. Everything is built on injector data.

The LT1 uses the SBC order and the LS1 does not.

LT1 1-8-4-3-6-5-7-2

LS1 1-8-7-2-6-5-4-3

Has anyone noticed the spark histograms reading half the air mass the PID table is? Started doing this after 2.24 came out.

An LS3 Camaro with LS3 ECU will not have the proper data.

Good points. I forgot to mention watching for when throttle tip in and when the WB is reacting. Mines a little slow and have to shift the readings about 2-3 frames.

Every time I've looked at the...

I'm seeing the burst knock as well. Your WOT VE/MAF needs some work. You shouldn't have to change the PE to get the AFR you want. Commanded and WB AFR should overlay each other. Add more to the...

You're probably going to end up using more timing.

Log Commanded AFR in the same area as the WB. Modify the VE to make the WB AFR match commanded. Your VE needs a LOT of smoothing. Ideally you'd...

Your PE should be fixed and not adjusted to get the AFR you are after. It's a target not a tuning tool(after VE/MAF is perfect can be used to get max power/tq but not to reach a different AFR than...

My LS1 with the below mods runs about 71% IDC with the LS3 injectors. I cannot imagine you'd be using another 30%. The exhaust has also been redone. At the power listed below the IDC was about 66%.

Keep in mind all E85 is NOT created equal. It can range from 51-85%. You should test it at every fill up. If your tune is spot on with pure gas then you should just be able to change the Stoich to...

I have since installed my LS3 injectors over the racetronics that I had. I have noticed that I have had to add about 10% to the VE in the lower area of the table. The reason being is that I had also...

The stft are just too volatile personally. The ltft's use the stft's for data but are a longer average and I think give you a better result. Just make sure you are using data with a higher count...

The Maf config is fine just make sure you follow the usual steps of isolating fueling to just the MAF or just the MAP based on which you are tuning.

The maf config can use either ltft or a wb....

Lol gee thanks. Ya I looked up the number and they are LS3 injectors. I have one last thing to try.

Well my one last thing was it. I had a weak ground to the fuel pump. The rail would show 58psi...

The LS3's are a great way to go. I just hope you don't run into what I have. My injectors seem to be flowing at about 50% capacity. I have to double my VE just to keep my LTFT under 30%+.

I've got the transmission out for a rebuild. I'll be back!
