I know is Plug and play, but does the ECU reconize it on the OBD2. Would it pass inspection?

 

OBDII doesn't see it. Yes, you'll pass inspection. My evo is tuned with ECU Flash with MAF-T pro in speed density mode, and I passed emissions with no issues. So handle your business, and get that MAF-T in there!

 

thanks much...ill get one here soon.

 

LT1, do you have any drivability issues using the MAF-T pro? I plan on using the MAF-T with a 3" GM MAF any pointers would be appreciated.
Thanks

 

No issues at all. Now I have it set in speed density mode, with a 2.3 ltr, 35R, 1000cc injtrs. No issues at all. The guys that tuned my car said they perfer the GM MAF. So I don't think there are any issues there. OBD II doesn't see, know or care that the MAF-T or MAF-T Pro is up and running. If you run it with a GM MAF, then the ECU wants that MAF signal, but that's taken care of by the MAF-T box. There is nothing you'd have to worry about.

 

Thanks a lot, I have the Ultimate Racing 35R turbo kit with 880cc injectors and want to get rid of the stock maf, I made 432whp@24psi using a 2.5 inch maf intake pipe which I know is too small. I just bought the maf-t and a 4" intake pipe, with 2.5" ETS upper and lower intercooler pipe.

 

Is the bulk of your tuning done in Ecu Flash?

I would almost assume they would have the Pro doing little but simulating SD?

I was all set to go to Pro and then I had a altercation with a bridge. Now that most of that is fixed this is something I would like to get back to.

So how do you like it?

 

ECU Flash is used for timming tunning, and the MAF-T Pro is used for fuel tunning. I like it ALOT. The fact that the car is speed density, and can go the emissions testing like the car is stock with a 2.3 ltr/35R combo is awesome. Well worth it if you ask me.

 

another stupid Q?

I got the maf and the maf-t. I understand how it works. My question is, do you guys tune your existing fuel map when you add the maf-t or set your ecu back to stock and use the maf-t for your fuel using the stock fuel curve as base. I guess you can go either way but i want to use the maf-t more for controling big injectors and not mess too much with the PITA scaling and latencies.

 

^I think that's the easiest way to do it. Are you going speed density or MAF?

 

maf for now cause i got it and i wanna get more seat time playing with it. There's 3 or 4 local guys that want to use it so ill figure it out and help them when they get it . I will get the MAF-T PRO in a couple of months and make that SD for my car.

 

im sorry, did you say stock base or current

 

Stock base, enrich with MAF-T. But you may be missing gains from not being able to change timming. But hey I realize you have to start somewhere.

 

ive been on ecu flash for a while, so i got her done now. I just want to get in the maf-t wagon. i hate to fight stock mafs with diferent filters and intakes and injector scaling

 

also, on my load, i got them scaled to like 300. do i need to go back to 260 (stock) or leave that alone also
