you dont want peak/hold, you want saturated. asuming this is an obd 2 sir....

Why ..can you supply me cheaper? ;) It's a t3/t4 with .57 compressor wheel and .50 compressor .63 turbine , should boost at ~3500rpm

I'm also still looking for injectors, RC doesn't sell 450 peak/hold :(


I have the smae project for a JDM B18C ITR..... RC sells 440cc vice 450

Why shouldn't I use low impedance? I read in the Honda performance builder's book that low impedance have a faster respons

Car is 1991 CRX 1.6iVT OBDO PR3 (euro spec, no knock sensor)

i was just thinking you were going with saturated because honda uses saturated injectors...

i wasnt saying what you can and cannot use! ;D

Mmm perhaps I should use saturated then , I'll throw out the box, saves me weight too.. I defenitely want to go with new injectors and RC are drop in

i have a JDM d15b SOHC. It recommends me to use the NGK ZFR6J-11 spark plugs. Which ones could i use that would be 1 degree colder? I have having a problem finding NGK #7 plug info thats in english. Also i heard people talking about the safc and vafc. Which would be better?

I currently have the Greddy 15G with Type S BOV and type 31 IC with a greddy blue box (yes i know it sucks).

Higher number=colder plugs. Use a 7. I think the part number is ZRF7J sumthin. SAFC/VAFC hack is the same thing for the most part. Most people with VTEC runs the VAFC. The SAFC can have a "blue wire" mod to read out output voltage signal from the O2 sensor.

get an AFC, 450s, and wideband tune.

perfect, no problems. a team of tuners here do wide band street and dyno tuning, at awesome rates, thats where i go.

Re:The truth about the afc hack!!!!!!!
 
I just read the complete thread and just still have a question about "Timing/Detonation"using the afc hack, after all this is the enemy we are all trying to avoid. At cruise/idle being not advanced enough by statically retarding the dizzy and still being far too advanced under boost like described in the ghettodyne timing map Joseph showed us on page 1 of the thread??
Now I am sure you are all sick of hearing about the BTM doing one thing "retarding under boost". Most of you dont use it. Most of you just plain hate it but I do remember the question from 2000psi- said but to get to 8psi you must first pass 6 psi. and there is gonna be time spent at 6psi....what about that?True if you dont want a high boost setup with over 6psi and you dont rippp it all the time what is your knok count going to look like??
MSD now has a BTM with adjustable advance for cruse/idle.
and then the BTM kicks the retard back in under boost/WOT???
Will this be the solution to erratic idle/gas mileage problems when using big ass injectors in turbo cars
