Re: ever tune DFI (miker61588)

Unless they have someone different than two years ago don't count on much help from accel tech line. That guy didn't know his azz from a double barrel shotgun. I found out that Lingenfellter had sent me the wrong map sensor after I changed that then the tuning was not hard but it takes time to get it right. Several on this forum have taken their cars to someone with a dyno and payed to have it tuned but since dyno can't duplicate real time acceleration you would still need to tweak it a little besides why pay someone for something you can do yourself and you will have the satisfaction of knowing you did instead of hiring it done go for it you can do it. :lol:

Re: ever tune DFI (black bart)

black bart you talked to the wrong guys at Accel. Lets see two years ago that would have been Charlie Trombley at DFI, he was a wizard and so was Mark Hamil who replaced him. Neither one of them are with Accel now, and to be honest I don't know the new guy but I am sure he know's what he is talking about. When you call the Tech line you cannot talk to Accel, you have to talk to DFI which is seperate company that is now owned by Accel, but a seperate location.

Re: ever tune DFI (snaketr)

That name Trombley rings a bell I think that is the one that I talked to I called him about three times and explained to him how it ran and what I had done and that I thought the map sensor was bad and he kept saying that I didn't have the base fuel map right. Well I found the problem myself it was that Lingenfelter had sent me the wrong map sensor. The one they sent me was for a naturally aspirated engine and it didn't work for sheet when the boost came up. :cheers:

Well, sorry too hear that. Trombley is a very smart man, I think he works for Mr. Meany now at Holley. I have not talked to him in a couple of years.

Re: ever tune DFI (snaketr)

If you are new at tuning and using the DFI 6.0 box you should find a shop that uses a stand alone wide band 02. This is the reason I would not recommend a DFI to anyone unless it is the new one with the wide band option.

DFI 6.0 was a good option back in the early 90's when it was the best option for the cost but with the wide band option you are able to tune a Speed Pro safely and quickly at WOT. Many engines have been melted with the 6.0 boxes in the hands of those that do not have experience or proper tools.

One thing to remember is no aftermarket computer is going to correct basic engine problems line vaccuum leaks and such. Nor will it fix a inadquate fuel system or incorrect injectors. This is another reason to have a shop tune the car. When you add this cost you will see that the Speed Pro is a good buy alnong with the safty of the wide band O2.
