I replaced the fuel pressure regulator with an aeromotive, the fuel pump with a walbro 450 e85 rated, and pid settings for lambda were messed with, it worked for my car: It idles perfect now this is a startup:

I'm going to head to a dyno just for kicks but looks like so far the car is in the 600whp range:


Boost is dropping off from about 20psi to 18 psi on the top end wonder if some cams would help or if some stronger wastegate springs are needed(running 8psi base), or if turbo is starting to hit its top efficiency range.

The real key here is your fuel pressure differential (it's 7.5 PSI higher on this log)... Not the pump or the regulator.

Yes i raised the base pressure thats all. Again changing the lambda pid settings is what sorted out my idle issue

F1TwoThousand

So far everything is sticking together mechanically and the injectors are pretty much maxed out, i do have room to bump base fuel pressure, maybe add some slight better wiring to fuel pump but for my current setup traction is the biggest issue which is what i was wanting to find anyway and winter has come so now it's just about time to lower the boost for the colder weather.

Good data, looks like you need a smoother road for tuning. Boost dying off at the end of RPM range could be a turbo sizing issue, unless you have some duty to add into the boost solenoid. Overall, good work!

Did you end up using the built in boost control solenoid? I recently bought an EFR 7163 T4 IWG and was wondering how to connect the controller to hondata

I've heard the standard MAC 3 port solenoid works better for some reason than the one included in the kit. Im using the one included in the kit and it works just fine for now

Started using boost by gear:

60-130 looks like around 9-10 seconds? What was your goal power wise?
