I'll be doing the VAFC hack on my 6lb JR setup this weekend and just wanted to make sure I my settings will be right. If anything that I describe is wrong please let me know. I will need to make the map sensor see boost but anyone know if I will need to take out the JR enrichment relay. THanks

What size injectors are you using?

GOKOU

Sorry about that. Using DSM 450 injectors and AEM FPR.

Hope I don't blow up my engine :D

My experience has been that I needed to add fuel at idle. The reason being that larger injectors take longer to open and so for short pulsewidths the fuel delivered is less than you would expect based on injector size alone.

After using my "Calibrating a modified fuel system" method I have found that ~-32 in the narrow band is better. -40 in the wide band is good and your crossover settings look good.

Looks like your pretty ready.

Thanks for both of your help. I'll try to mess around with it and see which settings will work. I'm currently setting my vtec point at 5000 where stock is 5500. I don't know whether this is a good point. I think a few people use 4900 or something. Hopefully I won't damage my engine.


Haven't seen you post for a while now 5 liter. Hope everything is going well for you. Are you fully tune yet?

What happens if you use a missing link with the VAFC Hack? i it is like destroying the entire purpose but how about difference in dirivability? what are the diff between with and without missing link.

Anyone else using different fuel pressure, trim or vtec settings?
