MAFS to MAP
Just another one of those questions that's really easy to think up but really difficult for Random to explain why it can't be done... rolleyes.gif
How hard would it be to swap out the MAFS on the US-spec Tiburons and replace it with the MAP used everywhere else? The advantage to doing this would obviously be so that we could use ECUs designed for these engines. What's the use of the MAFS over the MAP for those of us in the US? Is it emissions-control related, or what?

i think it has alot to do with emissions and other stupid US laws that keep us from getting fast cars like everyone else does. 
they were talking about this over there on the fxtreme forum not to long ago. go over there and try search you should come up with something. tongue.gif

Do to a MAFS to MAP conversion, you would have to also swap out the intake manafold, and the ECU, and probably splice a wiring harness or two.
The MAP sensor is IN the Intake manifold itself, so that is why you would have to replace that.
In theory, it SHOULD work, but for the measly gains you get out of an aftermarket chip the $$$ you would spend making the MAP ECU work would be better spend on other modifications.

Possible, yes!!!, worth it NO!!!. I do not think the investment is worth it, too complex and expensive, too much to change and then pray it works OK since there are so many electronics involved!!!
Stick to your system and look for parts for your system. Contact Alpine, and find out if they have a MASF system.

This is what I got when I asked Gavin at Alpine how much the turbo and super cost:
(that's $1900 for either) At fxtreme they said that this doesn't include the stuff to convert it to MAFS. Would it cost more than $1000 to convert to MAFS?

Mike,
Thank you for the e-mail. The cost of the kits are as follows:-
1) Turbo and intercooler: USD 1900.00
2) Supercharger: USD 1900.00
Freight to the USA would be +- USD 275.00.
Kits will be available in the next two to three months from our warehouse in
Ventura California.
Regards,
GAVIN O'LEARY

I'm not 100% sure on this, but I think It would be cheaper to convert their setup from MAP to MAFS than it would be to convert your car from MAFS to MAP.
$1900 Hrmmm...*drool*...*drool*

My Alpine kit works with rpm and intake pressure to control a 5th injector on the intake. If they are selling the kits in the US I beat they are not thinking to change your system to MAP. Their system has independent management for the 5th injector and therefore have a fueler box, I think they will be using the same rpm and intake pressure even wity MAFS system. ASK Gavin he is a great dude. The kit is a 1st generation unless they have a new one, right hand drive and eliminate the whole intake and get a cone intake to avoid my problem of a 90 degree rubber part collapsing above 3600 rpm before the compression turbine. Rated at 225 at 0.7 bar (10psi) but you can go higher with an HKS boost valve that fools the wastegate maybe can go up to 1 bar if you keep intake mix cool, a few things can make you gain extra ponies-
