It'* alot more complicated than that. Why would you even need that if you have an O2 sensor? Think about that. The AFC is an inexpensive tuning aid you use to establish numbers for a hard tune.

AFC'* are also notoriously unreliable. One member here has been through THREE of them. Imagine it failing and running you lean at WOT.

it was my understanding that the AFC was a more "permanent" adjustment before everything, and the 02 would still function as normal, adjusting for small amounts of rickness/leanness.
But in any case, i will hold off on the L67 TB idea.

AFC'* are not permanent by any stretch of the imagination. You need to tune MECHANICALLY first, then when no recourse is left, you tune. The AFC can give you the numbers you need for a tune, then it should be removed and put away until the next time you need it.

A PCM from INTENSE is cheaper than an AFC.

I never had any problems with my afc 2.0. I ran it for a few years too.. Many others had no problems as well..


But anyway..

Intense could just reprogram your pcm with the maf tables from which ever year L67 TB you use. (96, 97, 98, or 99+).

Be sure to port match the exit, fill in the coolant ports for a better seal, and re-align the stud holes.

does INTENSE do OBD1.5 hybrid PCMs? and if i let them know which TB i would be using, they could tune the MAF for that, and that would be all i need?

No, they don't, but then again, you didn't say which car. Your 97 is the more obvious in your signature on first glance.

You want www.gmtuners.com instead. Please clearly state which car in your next topic.

yeah, my bad. i wanted it visible because its for sale... but no sense modding if i'm selling.

GMtuners looks cheaper anyways:
descriptions are confusing me though... would i want
OBD-1 LT1 Flash PCM reprogramming..................................... $69.00
or
Custom Chip / MEM-CAL Reprogramming Service....................$55.00

or not even bother with the TB? i don't really want to get the custom burn JUST for that. but if it would benefit me quite a bit anyways, then i might consider doing the TB also.

Memcal.

Sounds like you need to contact them with your questions. Ryan (DarthFiero) is a member here. Give him a link to this topic and to Agrazela'* VE topic when you make contact.

thanks for all your help

Where in Minnesota are you? I'm in Burnsville and would be happy to lend you a Dremel. I've got several.
