I've chewed through the internet and am getting my arse kicked. Everything I find calls for MAF sensor input. Since I'm SD, I don't have that.

I gotta think there's a work around since a...

421cid engine. Whipple Blower. 10.2:1cr E85, big heads, valves, and a cam that's .65" and roughly (don't have the card in front of me) 240*@.05" duration on a 118LSA. 109mm TB, remote IAT...

Here is something I learned over the summer. I am also a newb so take it with a grain of salt, but its worked very well for me.

First, take a look at your IAC stepper count. Start the car cold...

Two tune files. One is "supposed" to work, but doesn't worth a crap.

Tune 1:

80961


Issues:

Ok, a little progress.

First. IAC was pegged at 340. To get it back to its range I opened the throttle body 1.25 rotations on the screw. This pissed off the TPS sensor of course. To fix that I...

First, let me preface by saying, "I don't know shit." I've recently been introduced to someone with about 15 years experience on this stuff. He's worked at a high level for some time and he's...

I don't have a MAF. It's an SD tune.

Thanks for the advise. I'll look into it and your tune file. Much appreciated.

Hi,

First, I'm a NOOB so take this with as much salt as you can. That said, I will speak in 2nd grader terms as I barely know the terminology/vernacular that the ninjas here throw around. This...

Aaah, yes. Thank you. Read instead of licking the screen...got it.

Please take a peak at the screen shots. I've set this up a couple times now using the tutoring section here and I still have no luck. It only populates the one field.

What am I doing wrong?

Right. I'm likely explaining this poorly. Say I have those two data points; RPM/MAP. I don't have the histogram setup however. It's just recording the raw data. That log is saved and archived....

Hi all.

Say I setup a function in the scanner for HP or whatever. Pick one... I set it up and see it working. If I was to go into an archived scan file that was done before I had the new...

Back at this. Idle seems a little better, but I still have a surge. Roughly 200rpm. idle goes way down when my fans come on. At a little bit of a loss to explain that one. One...

Indeed. data log.... Wideband is working, but it's not interfaced with HPT yet. I have a AFR500 from Ballenger.

I guess I have to set this one up manually. I don't see anything in the list...

That was a big step in the right direction.

I pulled a bunch of fuel from the VE table and updated the edits you suggested. It idles now. Still surges and the rpm is a bit down, but it's able...

This is a 3bar MAP sensor,

Can you tell me what/where I would update for this?

Appreciate the help on Bunny day. Thanks man!

1st tune. (rev_0)Wouldn't idle. Stupid rich. Got it started, had to hold at 1200+ to keep it running. Surging. Didn't have the AFX wideband connected correctly to log. ...

On that note then.


My car is a 2004 GTO. This winter I went a little crazy. 421cid LSX based, 2.9L Whipple, blah, blah.... In short, I'm north of $50K in the engine alone. All top shelf. I...

Thank you. So many ##'s get thrown around I just want to be sure I keep them straight.

The 2004 GTO's OEM "brain" is a P59 ECU correct?

Looked it over this am and made some alterations per your suggestions. Thanks again.

Slowly getting closer. Still have some key parts to fit up in the engine bay. Have yet to wire up the FF...
