I need to know what is the max I can and should run with this? I will also be getting the walbro fuel pump. I don't wanna dump anymore money into this car yet. I have a feeling in summer I may sell. I was thinking about the HKS safr because of WD Racing and the tuning he says. Will these 370cc injectors work with stock ecu? I was thinking about running like 7psi and is possibel when I feel comfortable 10psi with the rights tuning. What is needed for this. I was looking into alky like WD racing said and seems like a good and reasonable way to reduce detenation and cool intake air. Let me know

The 370's won't work with the stock ECU. The HKS SAFR or other piggybacks will be allow you to use them.

With 370's a fuel pump and a piggy back and I'm assuming a FMIC you should be ok for 10 psi. But you don't want to crank up the boost unless you have some type of knock detection.

Alcohol is always a good idea in my book. With the alky kit 10 psi is easily attainable.

By the way, its WDRacing without the space. Or WD for short...

hows this look? http://www.tuningtechnology.co....htmlI'm looking at the:The SMT6, which is $300Or SMT5 which is $220

It looks nice and seems to have alot of features. I'm e-mailing them to see if a knock sensor can be worked into ittoo.I like the idea of being able to hook it up to a computer. It seems to have alot of options based upon their screenshots.

Also does anyone have knowledge of what values to change and the such? I wanna have somethign like an example to go on. It seems that once I wire this into my care I should be able to see all the values of the ecu and what it is currently set at.? Has anyone done this to a Jim Wolfe ECU and seen the values? If so does anyone have this in a file and can send me for reference? Thanks

Sounds similer to the Power FC. Which works extremely well on the GTR's. The price is definitly right. Plus it controls ignition as well as fuel unlike the other piggybacks.

the nsport kit comes with a 7:1 FMU (same thing as a fuel pressure regulator?) and a fuel pump. Can I run this setup at 7psi or do I have to add 370cc injectors (and a piggyback)?

the nsport FMU is good for 7PSI and stock injectors but do not exceed this. I was running this setup and it was running a little lean but only during deceleration due to our computers cut the fuel off when delerating. When I would tromp on it though I was getting plenty of fuel.

The fuel cut on deceleration is not a problem. Since there is no fuel, there would be no detonation. Not to mention there would be such a small amount of air in the combustion chamber since the manifold would go into high vacuum as soon as the throttle is closed.
