Re: BMW Airflow Meter Swap How To: (rocco8v)
This Post is to update all Digi II owners on what chips are still availible for our injection systems. Alot of speculation is flying around as to what is actually still out there. I recently made some phone calls, and talked to some reps about what each company can do for us. Here is a difinitive list as of the date on this post...
Techtonics Tuning carries a DIGI II chip. Power increase is quoted at 4 to 5 hp, however TT claims there chip will work in only 1/3 of the ECU's, Bosch being the brand of choice. The price of the chip... $110 plus shipping. The chip also comes with a Knock Sensor spacer, available by itself from TT.
For those of you who can read German... here you go. This link is to a german tuning site, that claims to carry the DIGI II chip as well. The gains look pretty substantial from the numbers I can read, however, it is unknown at this time if the chip will actually work in our cars or not. Here is the link:

VW_Pilot apparently still sells the CSW chip. This chip works well for the price, however doesn't fix alot of the problems, but for the money, drivability is increased. Here is the link to his post:

SNS Tuning does infact carry 2 chips for the Digi II injection. One is designed for a cam, and the other without. Not much is known what the chip does as a whole, however, each chip only runs you $39!!!! It may be a cheaper alternative to some of the other chips on the market. Here is the link to their site:

Last but not least, AMS. Anyone you have talked to that owns this chip, will tell you. It IS the difinitive chip for DIGI II. This chip not only adds more fuel, but aggressive ignition maps as well. It completely ignores the coolant temp sensor once warmed up, and drivability and power are better than ever. Your Rev limiter is raised to 7000 as well. AMS however doesn't list this chip on their site, but it is STILL AVAILIBLE!!!!! Call AMS directly at (310)-763-8000. Talk to the rep and make sure you have your ECU type and number handy. This chip will set you back... $200 to $250.
There you have it. If you have anymore information on Digi II chips, please feel free to shoot me an IM, and I will edit my post.
