Ok I have a 2006 GT Vert, stock 4.6 engine with a Ford Racing CAI, stock cats and h mid pipe, SLP axle back pipes. It's an automatic with stock gears I think they're 3.31 and my tires are 235/50/18.

I'm using 93 octane fuel and after installing the CAI I get the lean condition code. Reprogrammed the ECU with Diablosport inTune, at first used the 93race tune then realized I should have used the custom 93R tune I got with the tuner from American Muscle/Bama Performance.

I haven't gotten the DTC code again but I may be talking too soon as it takes some time to show up. I check and rechecked the CAI for leaks and don't find any. What should I look at in the log files to see if I am running too lean?

Any help would be appreciated,
Alex

 

Wheres this 93 Race tune from?

 

Cavero, the 93 Race tune is a canned tune that comes with the Diablosport, it's not one of the 3 free custom tunes that comes with the inTune you get from American Muscle.

I drove the GT tonight about 60 miles and the check engine light hasn't come back on but I also didn't mash the pedal. I wonder if this problem will worsen when I get a ram hood from ABC Exclusive.

 

I think I would invest is a Bama tune, they do great work.

 

Does the DiabloSport have you set any parameters for the 93 Race tune? Just wondering if it wasn't set right for the MAF housing diameter or something along those lines

 

antdog, I did get a Bama tuned Diablosport inTune from American Muscle with free lifetime tunes.

Cavero, I didn't check to see if the 93 Race tune was adjustable but I think it is. It wasn't one of the custom tunes from Bama, I found those under the heading Custom Tune.

 

Im just wondering if the Built in tune wasn't set up for your CAI. Either way, i think youre probably good now with the custom tune

 

do not know in New York if the weights and measures test for octane ratings. here in Tennessee they only check pumps for you are getting a gallon for a gallon. you pay for premium but it maybe regular, who knows? the distributor could also be cheating the gas station, or could be winter gas.

 

Sorry my bad.

 

It sounds like you just had some trouble with the Canned tune. That's the good thing about running a custom tune, we can make any necessary adjustments if the lean code comes back. I would be surprised if it came back while you're running our custom Bama tune though!

Dan thanks for the input, I haven't gotten the lean code again. Seems I put in the wrong tune the first time. The second tune I loaded which was under the heading Custom Tune worked great. I was hesitant to chose that one first because I thought it meant I could create a custom tune.

Everything is good now.

 

Awesome man! I'm glad to hear you're not having any issues anymore.

Woops

 

Car runs great now, had to remove the SLP Loudmouths and go back to the stock exhaust. The droning drove me crazy and after awhile gave me a headache. I liked the sound, the deep throaty rumble so when I can I'll looks for something like that minus the drone.
