I am not trying to beat to death issues that have been discussed in the past... I have read all the articles on the FPR and V-AFC and I still have a few questions for those of you in the know!

For the Fuel Pressure Regulator it appears that the stock FPR can vary by quite a bit. If you replace the FPR will the pressure remain constant or will it vary somehow also?

There also seems to be a debate as to whether to run rich or lean? Was it determined that this is due to the StooK's behaviour to diff temp changes based on the geographic location of where your StooK is?

I read the threads about the dyno tests with the FPR, but I was wondering if someone collected the various settings that people were using and how they determined that was the correct FPR setting for them?

OK.. OK... the FPR actually brings up another issue Fuel Mapping! I know that the V-AFC is the tool for the job providing that you tune your car properly. Is there a harness for the V-AFC? If not is there someone out there who has installed the V-AFC and has the correct wiring setups?

I know that getting a Mugen ECU would remove all of the temp checks for the engine and will also redefine some fuel mappings, but I hate to lose the immobilizer feature.... besides I like to try and learn and do things on my own (for better or worse!). Is there anyone else beside Mugen who makes an ECU for U.S. Spec StooK's?

Do you feel that a FPR, V-AFC (properly installed), and Mugen thermostat could help with the car retarding performace based on various temp changes?

I guess living in the South where it can be 60 degrees F in the morning and 100 degrees F after lunch is making me notice some of the characteristics of the F20C.


I am not against being reffered back to the search feature... I may have missed something in my initial search and I apoligze if that is the case.

OK... lay some knowledge on me guys

 

I use a field vtec controller harness to splice in my V-AFC so i dont hvae to hack up the stock harness. It is about $200 for the harness so the price is high. That is fine for me tho because i'd rather pay that then have the dealer refuse service if something goes wrong in the future. Use the Helm's manual to know which wires to splice into. It worked for me on the prelude and the s2000. Of course, not the same locations tho. I spliced two harnesses differently for both cars.

 

Cool... thanks for the advice! If you don't mind me picking your brain...

What is your overall feeling on the V-AFC?

Do you use it to lower or raise your VTEC point?

How long did it take for you to tune your A-F mixture?

Is this something that you would recomend to another fellow StooK owner?

Do you also use a FPR?

Thanks a ton...

 

BTW .. where can i purchase the field harness??

Well I found a pic of it... (scratches head) I think!

I got this off of VTEC.NET.

 

The V-AFC is extremely helpful in fine tuning the S2000 and it eliminates the need for an aftermarket FPR. Ideal VTEC engagement is at 5600 RPM's which was determined through hours on the dyno, I believe Pepe will confirm this. The V-AFC helped me pick up about 8 hp, mostly at the top of the RPM range.

 

I jsut emailed Hondata to see if they would want to do a group buy.

Is the Field harness a direct application for the S2K or one for another Honda?

I couldn't find the correct harness for the S2K in Field's website.

 

I was under the impression that I needed to buy one for a 5thgen Prelude and use that one to hack into...
