I guess I'm gonna go do a few dyno runs at a local Mustang dyno to see what it makes there. It was offered to me so I figured I mightas well just for fun and to see how the dyno's compare around here. (I don't really care about numbers, I am just doing it so the owners can compare for future reference).I might get it to the track next weekend. I'm afraid to see how that goes...

 

mark is away until Tuesday.. i'll have him respond as soon as he gets back.. I do know that we would never send a car out of here with its air/fuel ratio in the high 12's.. you said the car was tuned here a while ago.. how long? was anything changed on the car since that point? you also said you bought the car from someone else.. could they have added something to the car after it was tuned here a while ago that would change the air fuels up??

I don't remember the exact scenario... you were promised that we would put the car back on the dyno to double check the tune and make sure the afr was normal.. the reason there was dyno time charged was because you had added a few things to your car which basically required a little bit of tuning (wasn't it a FMIC?).. hadn't you added anything new, I'm sure there wouldn't have been any charge to fix your tune, if need be.

his tune was off before adding the FMIC.

for a person that is driving 400 miles round trip to you, it seems only logical for him to add whatever small things on the horizon to avoid another retune. Just how he isn't asking you to reimburse him for the gas and other expenses to drive again down for a bad tune, you shouldn't have charged him for a retune that you were going to do anyway.

 

While I would have no issues with that if I had showed up for the tune with an extra part added without telling you about it first, correct on it being the FMIC. I explicitly stated when I called initially to alert you guys of the problem that if I am going to be retuned I would like to take advantage of it and put on the FMIC that I had sitting around. I believe I spoke with Smokie the first time and he said that wouldnt be a problem. I then called back a second time to confirm the appt a week later and spoke with the gentleman who worked on my car when I came down and said that it was noted as no charge in the book. See where I am coming from?

 

Sorry, I'm not trying to bash you guys or anything. I can get you guys the approx. date/time when the car was tuned from the previous owner. I did save the map that was in there... as far as I know, the previous owner didn't add anything since the tune that would affect the air fuels in part throttle or WOT.

 

The difference in AFRs from one dyno session to the next could have been a result of being in a different part of the maps, due to different temps for example. I'm a bit surprised with the posts from other disgruntled TurboTrix customers above. I will be interested to read Mark's responses.

 

We looked at most/if not all of those possibilities. It was just way off.

Turbotrix: I did speak with the previous owner, he said nothing had been changed.

 

Any chance the fuel pump is wearing out? Did you check fuel pressure at idle and under boost?

 

Well everything works perfectly fine right now except for the idle in the AEM itself, so I know it's not the fuel pump "wearing" out or anything. Everything tuned out fine and nothing was physically changed. I don't have a gauge or anything on the car to check fuel pressure.

TurboTrix: The car was tuned about July of 2005. Blue By You 2003 Evolution. I PM'd you guys about the car before buying it but got no response. I have the map if you guys would like to look over it again.

 

OK, to clear a few things up, the car was tuned the following Monday after Waterfest 2005. I don't exactely remember the dates but it was the monday following the Porsche/Audi/VW show in englishtown, thats why i was up there and on the way back I stopped at TT to get a tune and a few things installed and then drove it back to NC.


After the car was tuned that was it, I added nothing, changed nothing, touched nothing. There were some Idle problems with the AEM but that was all, and it seemed that if i let the car warm up the idle problems were solved and it caught just fine around 12k rpms.

 

If the pump were losing pressure, then lengthening the duty cycles could compensate, so the fact that it runs fine now isn't necessarily dispositive. If a car is running much leaner than before with no changes, the fuel pump is a good place to start as far as tracking down a potential mechanical source of the problem. In your case, maybe the tune was fubared, but I was just throwing out a possible mechanical explanation.

 

yes thats what he told us, thats why mark had told him to come back so we can figure out why.. and retune the car if necessary.. he was charged $150 for dynotime and to adjust his map for his new parts.. which weren't on the car for the original tune that he claimed was too lean.. we tune anywhere from 2-8 cars a day.. they are never sent out of here running lean..

Once mark gets back here on tuesday, i'll have him respond on here.. he will probably want to take a look at whatever maps you have.. please email them to me.. sales@turbotrix.com

-Mike

 

Your assuming your car was tuned by me .. I get alot of links from ebay potential customers who said they were tuned by TT .. and its not true. You come on and claim that i tuned the car and the tune was crap.. Please send me the map and the name of the guy that claims i tuned it. Where did you buy the car from ?

This is my first time reading this thread.. I can assure you that nothing leaves our shop ideling at 10.7 afr ... at idle... Had you gotten a response stating that yes i tuned your car .. then by all means there is merit to your post... Until you have that confirmation i dont think our name should be mentioned at all .. esp in a neg way
