Well I was going to boost my N/A rx7 but dealing with the cost of repair and everything it just didn’t seem like a good idea right now. Save my pennies and in a few years get an FD. I am asking you all because I know jack **** and this seems like the best place to find out information or at least get me going.

Let me explain the problem first the car I’m going to turbo is an 03Elantra GT sedan. Looks pretty tame but in Korea they already have a few Elantas and Tibs running 11’s. Now If we could get open dialog from Korea everything would be cool but we can’t and the help we can get are for Tibs only. For some brilliant Idea they stuck the same I4 in both cars but one is MAP and one is MAF. From what has been worked out the Elantra has a 1bar MAP sensor (the detail get kind of fuzzy) and can not read boost of any kind. When the OEM MAP reads above 5.0 volts it goes into limp mode and if you go past 4.5volts on the sensor for more then 4 seconds you hit limp mode.

Now the problem I’m having is If I can find away to trick the MAP sensor to think its only running at 4.5V even at WOT under boost. How can I tune using an SAFC-II so I don’t blow the bitch up? Will running a variable resistor to the ECU then splicing into the MAP give me a source to tune from? I have read threw the article on how to rig the SAFC-II up to read boost instead of using the TPS. Any info/help you can give me would be great I would just buy a turbo kit and be done with it but no one makes it. I can get the parts and everything to go turbo but making it run Is another deal. If I need to get a custom made MAP or something A link would be great.

Thank you for any and all help.

 

Go find links on turbo'ing a Honda.  They use check valves to prevent the MAP sensor from seeing any boost, and a rising rate FPR to get the fuel in.  Crude way, but it works.

Thats another problem we are having. We have a returnless fuel system and we are working on converting it to a return style witch would prolly be the best way to go and use a warlbro(sp?) fuel pump.

Now some questions about what you posted so I can use it to gather my knowlege base a bit more. By using a check valve will it effect the source I'm going to have to use for fuel tuning. I would rather not guess at it by doing some calculations and just taking a shot in the dark. Thank your RETed for all your help so far.

Is there another/better fuel managment that would be better suited for this other then an SAFC-II?

**edit**
We can't advance timing on are cars past 8degrees +/- or it starts throwing cells. It has been fixed with an MSD dis-2 "Don't know if that will help with any of your questions."

 

Yes, it's required.


It's probably the cheapest and easiest option without going full stand-alone.

Throwing cells?  Check engine error codes?

take a look at e-manage from greddy.
it has more singal altering tools and stuff.
