Maximum Boost on standard ECU?

[V8hilux]

Hmm, just re-read the thread title, I am running a Link ecu not a factory one anymore.

I am running an Eaton M112, air temps are getting up around 160deg on full boost, so i plan to run a bigger pulley and try bring it back into its efficiency range. Also running 440cc injectors. 7500rpm rev limit with no detonation.
Like Anodyne said earlier, a good tuner!

as a budget builder... I was thinking of 2 CT26 turbos from the 3sgte mr2. 8psi on stock ecu... but I really would like to go to a map vs maf and build a better intake.
my motor is the LS400 w/ the side intake and I would like a front/rear intake. I'm using the motor in a mid engine set up.

Welcome to forums...
Any pics ???

this is the car that the motor is going into.

What sort of vehicle is it?

WTF I just did a search on truck turbo for an image and came up with this P.O.S design

Hey look, dual-purpose intercooler pipes! Induction and roll bar.

its a Porsche 962 that I built from scratch... its got a 4agte and mr2 trans
ran 12.2 @111mph 2.69 60' no traction till 3rd gear.

going to the Audi 500cs trans for the 1uz. good for 500hp. Same trans as the 944 turbo uses.
I don't like the color either. it didn't turn out the way I'd hoped.
When I do the new motor and trans lay out I will need to move the rear wheels back about 9" and I will repaint it at that time.
This car is not ment for the Drags.. its a road race car. I just wanted to see what it would do.

Sorry I always thought a 962 had a flat 6 engine.

I may need to change my Username!

Please don't call it a 962 unless it is one. Then it will be worth worshipping.

 

[d962r]

the body is of the 962. it is a replica that I built. There were some Profab cars that were build using a V8. They were also 962's. That is the make and model of the chasies. like a spice buick, or Raynard/Ford vs Raynard/Toyota.

I never asked to be worshiped... I just want to make it run and handle better with the proper weight placement and wheel base.

Its a shame seems like good looking stainless work. Surely there is bulk space under the tray to put it. Then you keep the load bed empty for carrying stuff.

Not that I can talk ..
Can we stay on topic ??...
We need a B.S forum ??

The only real limitation of the standard ecu is the air flow meter its not the amount of boost it controls its amount of air it flows . They work on a 0-5 volt signal and once it reaches max output the ecu has no idea what to do next except throw up a fault code and go into limp mode .

Actually, the afm on the 1uz is the karman vortex type that operates on frequency and not voltage.
