I'm planning to be putting a turbo on the car and I have an RTek 2.1 installed and have been doing some rough street tuning. My question is this:

The map on my RTek 2.1 only registers vac and only allows me to alter the vac. Is there an update or a appendage to the software that I can download that will allow me to alter the fuel map for positive pressure? I understand that the fuel map maybe limited to the hardware on the system, but I thought (perhaps incorrectly) that the stock MAP could read up to 1 bar; so it wouldn't be 0in HG or 0PSI but 14.7 PSI?

I know the fuel map is limited to 14x14, but is it possible to get another 14 instances for the positive pressure readings? If it's impossible will I just have to set the upper portions of the stock MAP to be richer than normal. That doesn't exactly give me whole lot of resolution though.... Thoughts?

 

No, we always recommend running a turbo ECU, AFM, and MAP sensor from a turbo whe doing a conversion.

 

Alright, well now that I know that it's kind of tough luck for me then.

So what are my options? I purchased the RTek for the ability to alter timing and adjust fuel, I know that Aaron was able to pull off the 6-port turbo with an SFAC which only alters fuel similar to the RTek. I should be able to do the same, yeah?

Should I just tune it using the WB and hope for the best?

 

Well theres no easy way to make the ECU 'aware' of boost. The AFM should make up for the additional airflow along with tuning. You can also try a rising rate FPR to help with the fuel demands in boost.

 

I was already planning on an raising rate FPR.

What are some of the not-so-easy ways to have the ECU become 'aware' of boost?

 

All of them writing large amounts of code, which can all be replaced just by using the turbo ECU as it would do the same thing without writing additional code.

I'm sure there are other people that have done it (before the rtek came along) so maybe they have some ideas on how to handle the fuel/timing in boost..

 

Doesn the Turbo ecu also retard the timing? therefore wouldn it eliminate the need for tuning the timing on the rtek and only leave you with the need for tuning in more fuel and maybe adjusting idle?? jw goin with the tII ecu with rtek 2.1 myself and read somewhere that it retards the timing...does it?

 

I also have a Turbo car that I put a Non Turbo engine (six port if you must) in. I use a RTEK2.0.

So there is no problem as long as you use a TURBO N332/N333 and a Turbo AFM and Turbo boost sensor. But my Turbo car came with those. So what's the big deal.

I also have a non turbo car that I put a turbo engine and transmission in. Plus the Turbo afm and turbo boost sensor and Turbo ECU (RTEK2.0) and as COMMON SENSE DICTATES, used all non turbo harnesses.

COMMON SENSE dictates you do not use non turbo afm/ECU/pressure sensors with a TURBO ECU. Those parts are dirt cheap.

That should answer several of the threads on this site.
