what exactly is a 749 swap? Thanks guys

A 749 ECM swap is what people change from if they are planning on running a Supercharger or Turbo on their cars. They can start like I dd using a 165 ECM which is basically for Mass Air Flow systems. I then had repin the entire ecm to swap to a 7730 which gives me the speed density and then do a minor repin to a 7749 ECM which allows for Boost control. The main reason alot of people do a 749 swap is to run the $58 or the new $59 code. This swap isn't really necessary and it can be done with a 730 ecm but I was never able to get it to work properly. To swap to a 749 takes about 1 hour and a purchase of a new Map sensor (usually a 2 bar on a $58 and a 3 bar on a $59)

That's all new to me. Does the $58 and so forth mean it cost 58 dollars?

Not even a close guess. The internal guts is what is called the $58. This is the basic program or the PROM or so called mask inside the ECM.. The 165 ECM uses a $32, The 7730 uses an AUJP chip and I believe is a $8D on most occasions. So the 7749 has to use it's own mask or prom and that is a $58 for a 2 bar map and a $59 for a 3 bar map sensor. If you are planning a turbo or S/C I would highly recommend on running a 7749 with a $59 mask. YOu can learn more about the $59 on

Everything that I have talked about above is what tuners use to help get their cars run better. You do need special software and equipment to use 99.5% of this advise..

Things that are needed

Laptop
Autoprom or Ostrich
Ribbon Cable and EEProm Adapters
Tunerpro or Cats

Thanks for all the information. If the car has that already and I don't plan on putting a Supercharger in it, will it run alright with out that?

Thanks

Not exactly sure what you mean "if the car already has that"

.. Has what?

.... that was funny!

Looking at maybe purchasing one and he said it already has the 774 and $58 done to it and if I get it, I don't plan on charging it. Will I need to remove what has already been done?


Thanks guys
