The density table can play into fuel and idle control more than anything else in the tune. You'll see it come into play with cold start to hot idle...

If anyone is willing to teach me how to fix this I am more than willing to pay for their time and knowledge. I do not want someone to tune the car, I...

That was a good guess Alvin. I worked at FAST for over 23 years before I began my full-time tuning career. I was there back in the day when it was...

Yep, I'll be sending off the donor PCM and emailing the stock calibration file. Then it's just a matter of waiting the 10 - 12 weeks for the Whipple...

Wideband looks like it's working to me. The VE problem isn't anything to do with the injectors. Here (arrow) WB shows lean, as do NB's. After...

Info from web said this is how you do it on the Camaro i have. So far its working alot better. PSI is so much more than before. understand, ...

Everything is working as it should in that log. Converter locks when it is asked too. Max temp reached was only 145F and TCC slip issue normally only...

Nice!! Yes sir I completely understand what you are saying now! I mean it ALWAYS has been important of course even going back to gen 3 LS...

Have you checked the voltage output for the gauge with a voltmeter to see if it's that erratic?

What O2 sensors are you using? (brand, part number, application same as the tune file?)

Good deal. I would imagine now it's just a matter of sending everything in to them.

Beta fixed it up for me ... I now see the MPVI3 in the "Help" menu ... And when I went to get config, it prompted me for an interface...

Yeah, I don't think it works that way. It's not a boost a pump. Setting that table to 14 does not mean you're applying 14 volts to the pump.

Solved the dead pedal issue by disabling desired airmass logic all together. However, now the issue of dying after the 2 step is back. Any ideas?...

Just about every calculation that the ECM has to do starts with what's in the injector data tables, which are no longer correct for the ones being...

Thanks Greg; Appreciate the info.

A lots changed since this thread, but there are some background tables that will help - you may even have one or can get hpt to add one which is the...

I now the thread is old but I don't frequent often. You are aware the moates quarterhorse plugs directly in to the programming port on the back of...

Just a FYI i did make some changes after i posted this. System General Fuel System Volt Min 12.5 to 14 A scan shows that Fuel Pressure...

Exactly. That's what I think as well. Although HPT and Whipple (this is in preparation of a Gen 5 3.0L Whipple) both confirmed they could support...

Thats it. If its in the same size housing as it was prior you may not need to mess with it much. If you were using the in maf IAT then you will...

Majority of them are enabled still... Try logging the mapped points and put your theory to the test. Id be willing to bet its using a ton of MPs. You...

best bet is to tune these with a moates quarterhorse and tunerpro rvaf1 can run a cvaf1 cal- USUALLY

Here's your problem. That vehicle is not covered yet.

Thanks for your help, I really appreciate it. Feeling that much closer to getting this thing running!

If you find the thread, read it, and still have questions let me know.

Let me search your thread on the offset. That spreadsheet doesn’t give you the multiply by whatever it just gives the voltage and an offset if you...
