if my funds were there for stand alone I would do it. But I am stuck with doing JWT Items because of cost and ease of installation. Plus I need a car to drive daily and I dont have time to play with dyno's and charts just yet!!! Have a good one!
Maxed out 370cc inj. at stock Boost!
Well I have come to the conclusion that I am maxing out my injectors. I put down 246.9whp and 212.0 ft.lbs. on a stock pulsar t28 at 7psi. This is with 370cc injectors. I have a bored Stock maf with a 3bar JWT ECU program. I dont know where to begin. I dont want to go with 50lb. injectors just yet. I am waiting for the winter! What do I do for the time being??? Thanks and have a good one!

Sorry I forgot to answer your post. The way to tell for sure if you are maxing out your maf is to measure the voltage of the singnal wire to the ecu when you are WOT in third gear past the torque peak. If you are pulling more than 5.1 volts, then you are maxing out the injectors.MarkSR20 said:Well I have come to the conclusion that I am maxing out my injectors.

Thanks Mike for answering my post. I hope all is well out there in california. I will keep in touch after I do the test to see how much the car is reading for voltage. Thanks again!

The only way you can tell if your maxing out your injectors is by checking the duty cycle not the MAF sensor.
Not true on the injector part.morepower2 said:Sorry I forgot to answer your post.

How do you think a tech tom or a consult calculates duty cycle?
Mike
Bullshit. Don't call me on this when you don't know what you are talking about. The injecotrs are at max duty cycle at 5.1 volts. On a Nssan, the fuel table address location is driven by RPM and MAF voltage.W10DET2020 said:Not true on the injector part.

A listen here book smart.
It might so happen that stock 370cc max out at a equivalent reading of 5.1 volts to the MAF but this is not by any means the accurate way of doing things becasue.......... say if I had 400cc injectors and my MAF pulled 5.01 volts my injectors would be maxed out, no, my MAF would be maxed out NOT my injectors.

Do I hear someone challenging Mike K. on this? I want to hear more. Thanks, sorry I havent checked the car out on this situation. It is pretty damn close to being maxed out if it is not! Thanks
No they would not. Read what I wrote instead of trying to justfy your opinion.W10DET2020 said:A listen here book smart.

I've just recently been told that JWT will send you the chip and you can swap it yourself. (It's supposedly socketed) I did my VW's chip numerous times so AS long as its socketed then it'll be easy. That eliminates the down time 
They do require a 500 core until you send back the old chip.

Mike, just admit that you don't know anything about turbos or tuning a car. Its okay, we will still like youmorepower2 said:No they would not. Read what I wrote instead of trying tio justfy your opinion.

I had a thought along those lines. Anyone think about using a turbo timer to display the MAF voltage. Some of them come with o2 and/or battery monitors. What about running one of the sensor lines to the MAF signal instead and using it as a MAF monitor?morepower2 said:Sorry I forgot to answer your post.

Hello,
Apex SAFC monitors the MAF voltage as well and the Apex TT monitors A/F ratio or O2 sensor voltage which ever you perfer as well as a battery voltage indicator and either manual or auto turbo timer.
