Bob - That looks almost the same as the software I used on my fuel injected Harley. Maybe it can be used in this application...download it from my MediaFire link. http://www.mediafire.com/download/ki...ERT_Pro_CD.zip

I hardly ever head down south, so I don't even know of the Wendy's cruise in. I do often check out the A&W at White Oaks on 137 ave since I live pretty close.

Re: FITECH EFI TUNING tips, info sharing, ideas, settings, etc...

I'll post this hear because Bob has a 71 and recently did a gas tank swap. Can someone verify what all these lines are? Particularly the one in the top right.

I think front left to right it's feed line, return line, 3 vents, and unknown.

I can see where they go to the tank, but where do the 3 middle lines and the far right line go towards the front of the car? I'd like to remove them all if feasible.

Sorry, I might be cheating a bit...I open up the excel files in a program I use for plotting data at work. Its pretty powerful, and overkill for the FITech recordings, but I am better with that than I am with Excel...

Excel on its own won't make the best colorful graphs, try looking for a contour plot "add in" for Excel. The problem is we have 3D data with X, Y and Z components.

The FITech software allows you to look at the data logged files as well, and would be just as good for looking at transient traces, however, I could not figure out how to make any 3D plots with it.

All is not lost, you can still use the Excel, but, how much you can learn from the data will rely on which datalog screen you record. The Dashboard or Basic Sensors screens are general overviews. You will have to log the "Fuel Learn" screen to record the specific fuel learn data.

The plot below is from Excel, Showing engine speed during a drive and fuel learn adaptation at 3000rpm/50 kPa MAP, which happens to be where I cruise alot. 100% is baseline, so this is pulling 20-30% fuel in the learn based on how the fuel trim needs to adjust to meet target AFR.

So far my only complaints are the lack of documentation on the controller, and the number of channels you can log at the same time, or lack thereof. But at the FITech price point, I can't really complain too much. That and the fact that the K-line software did not come with my device to conntect the handheld to a laptop while driving, and their support has yet to send it to me...I guess a call is in order tomorrow.

Good luck! If there is anything I can help with, let me know.

Chris, I'm about 1/2 way between both. I will try to get to the A&W sometime by the end of this month. That's Thursday night for the A&W - correct.

This for Bob - they don't have mine yet (FCC) but I will be shipping it back tomorrow or the next day. They also said they would refund me as well. I followed your lead with the Tanks Inc gas tank. Finished the install last night but life got in the way today of me taking out for a test drive. Tomorrow's a new day.

Here's a few of pics of the install:

Friday nights.

Since everyone is looking for refunds from them. I sent them my $57 bill to ship my defective EFI-8 back to them, haven't heard back yet.

Mine all went to that emissions "item" that is behind the rear seat. I can't remember what it's proper name is, know it's emissions related.

Since I have nothing else emissions related on the entire car, I simply disconnected all hoses from that area, and only use the ones, including venting, included with the new tank setup.

I already had a vented gas cap, and ran the TanksInc vent valve around and over the tank, bolted in behind the rear valance. Never a venting issue, and never any "hiss" when removing the gas cap.

Hope that helped.

Yea, you're definitely cheating a bit, LOL. I was under the assumption that these graphs and charts were accessible from us average Joes...

Re: FITECH EFI TUNING tips, info sharing, ideas, settings, etc...

OK this morning I had the first fire since changing from the FCC to the Tanks Inc EFI. She started right up - had to tighten 1 coupling a little to stop a small drip.

Didn't change any of my previous settings. Had a couple of short drives and pushing it a little harder each time. Then it happened again as in the beginning with the FCC. I'm getting 1 or 2 pops out the side exhaust whenever I shift from 1st into 2nd into 3rd. It also happens in the garage whenever I rev my engine over 3500 and let off the gas a couple of pops out the exhaust.

I'm not sure what I need to change to stop those backfires. I have adjusted the AFR ratios a little richer and that seemed to quite it down a bit but still pops. Never popped with a carb. ever.

Here's a few pics of my handheld screens maybe someone can spot something here: 1st one is my AFR in the efi tuning section. The other 3 are just basic sensor operation. But if there is something here that someone can tell me what to change I'd be grateful.

Wayne, I can't see the pics on my phone, but we're you the person who had changed the IAC LOOP settings due to a hanging idle before? If so, maybe try lowering it back a little and try it again? If not, disregard.

Thanks Bob, tomorrow I am going to play with a few different settings and see if I can sort out this problem.

Re: FITECH EFI TUNING tips, info sharing, ideas, settings, etc...

Are you saying your having the same exact problem as when you had the Command center. Can you hook up a fuel pressure gauge and see what the fuel pressure is when the problem occurs

Fuel press. gauge on and reading 58 psi. I pulled 3 plugs this AM and all of them were a little lean so I'm going to play with the AFR settings. From what I understand from some fellows is to adjust rich first then go to lean after if need be.

I had that problem originally but I also had FCC issues - fuel starvation, falling flat, hot fuel because of location. So now I've eliminated one problem but still dealing with this.
