Please Review My Logs and Tune - Bad Shop Tune...?

[Doric]

2004 A4 GTO

Tune

Logs

One of the logs is from July 20th, before the tune. The rest are after. Note: I do have an AEM wideband in the car, but do not yet have the ability to log its output in HP Tuners.

The shop that tuned the car came highly recommended.

Relevant modifications to the car:

• STS w/ 60-1 @ 6psi
• Custom cam 224/220 .600/.600 114 +4
• PG dual valvesprings, Comp pushrods, dual roller timing chain
• Kenne Bell BAP
• SVO 42lb. injectors
• Speed Inc. fuel rails

I greatly appreciate any help and/or advice you guys can offer. Just based on what I know and the little input I've gotten so far, the tune seems weird at best and downright dangerous at worst.

Thanks.

I hope you didn't pay much for that tune. As the screen pic shows, not much was done other than adjusting the PE table to command as high as 10.4 AFR!

The IFR table isn't set up right either. And every trans table is still stock.
Looks like closed loop is disabled as well.

I paid $500 for a 'complete' tune that took them 9 hours to do.

The biggest thing I see is that you have a 1bar tune on a forced induction car. Its probably worth getting a 2bar tune on it. Also, I am not getting a wide band trace on the logs, so its hard to say if the fueling is right, but, on the plus side, at least the spark settings look good.

Does the car run well?

[Doric]

No, not really. That's part of my gripe - it only put down 395rwhp on their Mustang Dyno.

[Russ K]

You can do a Maf tune with only 6 psi.

man this makes me think i should start tuning. I see crappy tune after crappy tune and people are being ripped off. I could charge half of what these so called pro's charge and do a much better tune

If I were you I would go back to the shop and let them know what kind of amatures they are and ask for half of your money back atleast.

Good luck on getting this sorted out

Sorry for the noobie question Russ, but my MAF maxes out at 5000rpm on my LS2 with 6psi boost. Doesn't that mean its time to go SD? Preferably 2bar?

[Doric]

Update thread.

It's a long read, so the jist is that I asked the tuner to give me my money back and they've essentially told me to take a hike. I'm out $500 on what amounts to nothing more than massaging of the PE table.

Wow!!! I can't get to the tune or logs here at work but just by reading the GTO forum thread I have never seen such an example of, for lack of a better wdescription, wicked poor customer service. Actually it's just pretty much lying.

Couple qusetions:

What did you want them to "calibrate" on the AEM? Adjust the voltage offset to make HPT match the gauge?

Like I said I can't get to the links but are you saying that the AEM was reporting a worse AFR than when you took it in?

Post the tune and log(s) here directly using the attach function.

No, I had an Innovate LC-1 before the AEM. It never read more than 10.0, which obviously couldn't possibly be correct. So I verified the wiring myself but never went through the calibration process. When I took it to them, I gave them the Innovate directions and said, 'calibrate it to make sure it works,' after they relocated it. They relocated it, but didn't bother with the calibration.

I found a great deal on the AEM, so I uninstalled the LC-1 myself and replaced it with the AEM.

You got it. Attached are the four logs I've made on their tune, and their tune.

On the 25th, I sent in my old HPT serial cable for the upgrade to MPVI Pro so I can start tuning my car myself. It hasn't arrived yet.

[5_Liter_Eater]

So yea, they upped the idle by 50 RPM across the board, changed your IFR table for the 42#, and I agree with Russ that the IFR #'s aren't 'correct' although they are close enough to 'work', basically disabled closed loop over 100 degrees IAT (weird), richened up your open loop EQ in the upper ECT and MAP range (also a bit weird), forced the hot PE Enable TPS table which has very low TPS #'s (ok, whatever), used the PE to tune the AFR and took one degree of timing out (one degree for 6# of boost?!?). The real kicker IMO is they left the tranny tables bone stock.

Anlysis of logs next. When was their 'tune' done?

[Doric]

The tune was done on July 20th.

[5_Liter_Eater]

Can you post your config file?

[Doric]

Unfortunately, I can't. It's on my laptop, which is at home. Is there something in particular you're looking for out of it?

[5_Liter_Eater]

It's just a lot easier than setting up a config that has all your PIDs and histos to be able to view your logs.

[Doric]

Gotcha. Honestly, it isn't that much different from stock. So much so that you can assume that it is stock. If that makes sense...?

[5_Liter_Eater]

I'm not seeing a WB PID in your logs.

[Doric]

Right - I had a serial HPT license during this process. I was watching my AEM and the laptop in between quick glances at the road.

I sent in my serial cable and ordered the MPVI Pro back on the 25th of July. As soon as it comes, I'll be able to log my A/F in HPT.

[5_Liter_Eater]

oh, gotchya. So there is really no way to tell what the AFR is in these logs then. Did you log the dyno runs?

You can see from the log that you are entering PE when you aren't really on the throttle because of the hot enable PE being so low. You're not logging commanded AFR but your tune has you commanding ~13.5:1 from 1600 RPM to 3200 RPM. What you're actually seeing I don't know.
