Unfortunately I cannot post on hp tuners forum for some reason, so if anyone is willing to look at my current tune and some logs I have Id really appreciate any help. Ive been working on this the last couple of days.

pm me with your email and Ill send them.

Thanks,

John

 

You can post it up here so anyone can help you just need a good log with cruise, idle, and pulls. Also take it out of gear when slowing down so it doesn't mess up the log any.

 

aaaa

 

Can you post all of your mods as well? I see a few in your sig.

 

60lb injectors, 2.7 pulley, windshield wiper meth mix, CIA Header 1 7/8 inch And 3 inch Dp into Hahn 3 inch cat back, RAW 3 inch intake, CXR heat exchanger and stock HE

 

The tune you posted has a few things wrong with it. Fueling (Injector Data) being a big one. The IFR table is maxed out in most of the cells.

No biggie, there are a few places to find out some better injector data or how-to's to properly setup the IFR table without maxing it out.. The Redline Forum has a spreadsheet with IFR data and Flow Rate Modifier table data to make it so your not maxing out the IFR table. Also, the spreadsheet includes the injector offset tables, which the creators say a ton of research went into.

There is also a write up by SJSchafer that take a different approach, maybe even a bit more customized approach, then copying and pasting values from a spreadsheet.

There is also a How-To in the tuning section on this forum as well for injector data.

I used part the spreadsheet data that 04Redline and Omega_5 put together, which has worked fine for me, but I also "tuned" the short pulse adder table to help fueling from bottoming out because of the min pulse width not being able to go as low as we would like. I found "tuning" this table helps with bucking here and there.

The closer you can get your IFR table to reflect the actual slope of your injectors, the better. So using the flow numbers included with your injectors, if they were flow matched and tested, would be best.

I also see your running your MAF and VE table blended all the way until 7000 rpm. Were you trying to disable the MAF and run VE only so you could tune the VE table?

I would lower the values in the PE Enable TPS table, as you are hitting alot more boost alot lower in the rpm range than with a stock pulley. Don't forget to get your PE table in line as well. THe links I post at the end should go over all of this though.

Anyway, after you get good injector data in there, once you start the tuning procedure for the VE table and MAF table, everything should start falling in line, assuming you know the procedure. Again, the links at the bottom of this post should help you out with that.

Here are the links that should help you out, some I mentioned about above. I used Tiny URL to link to the redline forum post, for some reason the mods here don't allow linking to that forum:
