Question (as usual) :]

[s383mmber1]

Ok heres my set up. (main things)

NA-T
cometic head gasket
ARP's
BIC DDP
CT-26
Hard pipes
Intake

Now im going maf-t pro. I figure ill hit fuel cut without a a/f controller. Now

Can i use maf-t pro with the stock turbo injectors? Will they do the job of avoiding fuel cut while still staying safe?

I will get 550's this spring, but im just thinking if itll be ok with the stock (440's?) injectors.

Thanks for your time gentlemen!

Keep the boost down you won't hit the cut.

 

[s383mmber1]

Keep the boost down you won't hit the cut.

What do you suggest? 10-12 PSI and i wont hit cut?

 

[JustAnotherVictim]

Probably less than 10, I would think 8 or 9 may be safe. I'd get an aftermarket boost gauge since you'll have a tough time actually reading the boost with the stock gauge.

Make a wide band setup your next investment, then you will know your safe, push up boost a little at a time and watch your a/f. Are you going with speed density and boost control?

JAV- Remeber im NA-T so my voltemeter won't read much boost

I thought that with maf-t pro it had a wideband built in. :dunno: and yes it will be S/D and boost control

 

[tookwik4u89]

Nope , you need to buy a wideband seperate, s/d & b/c is good, your good on fuel control for whatever upgrades you make in the future, along with wideband and afpr. If you can monitor a/f safely, you can increase fuel pressure a bit instead of running inj duty cycle higher and get a lil more boost without fuel cut.

huh idk were i got the idea of maf-t pro being a wideband :dunno:

Thanks guys for the imput so far! Which widebands would you suggest?

 

[turbodhbar]

If you drill out the seal over the adjuster on the AFM . you can back the screw out some and raise the fuel cut. I've done it and don,t see fuel cut till 14 psi of boost.

 

[tookwik4u89]

I would not reccomend the AEM, just because some people are having issues with a/f ratios matching up with the pro. I have a dynojet wideband commander, I love it but their is probably cheaper alternatives, I bought it because it has internal datalogging for rpm, a/f & tps, without needing a laptop in car to record, plus it has controlled outputs for nitrous, etc. Not sure what the other guys are using....LM-1?

You can get the LC-1 w/ bosch sensor for $200
You can use the MAFT pro as a wideband 'gauge' until you can afford another $200 for the XD-1

Keep in mind i've never used the MAFT-Pro, but have read alot as I plan to go with this setup!

It'll work fine with 440 injectors if you set it up correctly

Forgot about that. :biglaugh:
You getting a thick MHG or stock size?

 

[NewWestSupras]

Innovate LC-1 WB was recommended to me to run with the Maftpro. DrJonez is the man to talk to. I haven't set mine up yet, so I can't give you an evaluation.

I thinkg I didn't remember yesterday is since you have increased compression from na-t you need to run lower boost levels to avoid detonation. I don't remember or think there is an exact boost conversion but 11-12 psi is like 14-15 psi I think.
So I would run maybe 5-6 psi just to be safe.

Yup 100 percent right there.

But when i put it into the real world. I was more than happy with my NA's performance. I actually thought it was kindda fast.

I think ill be plesently surprised with fuggin 6PSI.

 

[Jaguar_5]

I'm sure you will, but it won't last!

Every supra owner eventually decides they need more boost :evil2: :evil5:
