So i have an appointment for a dyno session tomorrow to tune my MSPNP,
Is there anything i should point out to make sure the tuners cover?
Like the After start enrichments so it warms up nicely. you know the small things that help.

I currently have installed are:
-305cc Supra light green top injectors
-Rx-7 Turbo II fuel pump
-2.5 custom exhaust
-16g DSM
-fmic
-mspnp

how much WHP can i make with this set up?
im looking for no less then 200whp?

Thoughts to both questions?

Thank you

you should be able to make 200whp. set your spark plugs at .29 gap so they dont blow out. best if you have a cold plug heat range 7. bring extra tools just incase you blow off anything. make sure you have a full tank.

180whp
I wish I can log into megatune so I can tell you..but make sure you leave with good idle and after you get off the dyno..do a street tune also..if possible...it made my car run super smooth...

What do you have for a radiator? If anything will limit you power-wise, me thinks it'll be your injectors. Unless you're absolutely clueless about it, you don't need the dyno operator to tune things like ASE. You can do that on your own time.

advice:
Tell them to go for MBT in every cell. Go richer if you need to increase spark to get there within reason. At less than 22* advance, you should go richer than 12.0:1 if its a street car...lower if track car.

Make det cans for detonation detection, don't expect a knock sensor to do it for you. I could hear detonation through the det-cans that the KS wouldn't pick-up.

Get a log for the final pulls.

This is the stuff I did when I tuned, someone will probably say that I'm wrong.

hustler what are det cans ??? and how do they work?

**** the small things, tune the important things like spark.

right now i have cheapp autolite platinum and would like to get some NGK's.

Which NGK plugs do you guys recommend?
a part number would be nice =D

I'll also say 180whp on those injectors. How do you expect to make 200% of the stock whp on 113% of the stock injector flow capacity(265)? Do you also have a rising rate FPR or something you haven't mentioned?

don't go over 82% duty.

Why is 82% the magic number?

i have a cheap'o ebay fuel pressure regulator, but its not installed. i took it off and put the stock fpr back on when i installed the mspnp. i thought fuel could be controlled through the MS?

should i put the FPR back on? do i need one installed?

i have a rx7 turbo II fuel pump installed and i know it pushes out over 200LPH

your injectors max out at just under 200 whp. that's just how the math works out, doesn't matter how much your pump can flow or how much the MS tells them to open, they can only open so much.

hustler

because from 82-87% duty they're open 100%.

that's kinda precise there Mr hustler.

Personally I aim to never breach 85% (and currently don't go over 65... (bit overspecced)). Everything I've ever read/been told is to aim for no more than 85%DC. That said I've known people get to 90-95% with no issues, but that was their risk, and not mine.

The closer you get to 100% the higher the risk that you'll lock the injector open/closed. Saying it'll happen at 82-87%DC is just plain wrong though.

im off to autozones to pick up a new set of plugs and then to the dyno, let you guys know the results after =)

let us know the process you went through to tune fuel and spark on the dyno!
