Just wish it was setup on the dyno.

Doesn't matter really.... it's still going to pull like a train and you are still going to make it slide!

Race time matey!

Bum dyno happy times wins over paper anyway

I think your right. I dont know if i had the final drive right. I think if you multiply all my RPM numbers by 1.1then it looks alot better. Multipling by a factor of 1.1 is like the difference between a 3.9 and a 3.545 rear diff.

The later model STis gearboxs have a 3.54:1 rear diff ratio. BUT they have a 1.1 multiplier in the transfer to the rear. So the final drive is still technically 3.9:1, even though the rear diff is 3.54:1. Its a funny thing they do differently compared to the early sti boxs. I think i miss calculated miss-understood this when i did my numbers.

But if you multiply every value by 1.1, it seems to make more sense.

For example if you multiply my last RPM value of 6372 by a factor of 1.1. You get exactly 7009.2 RPM. which is spot on for a limiter of 7000rpm.

And if you multiply my 3600 rpm where i thought boost comes on by 1.1, then you get 3960 rpm
Which might be about right for this setup?



I think the SubaruGear calculator is set up for the average person who doesnt understand the 1.1 multiplier in the later model STi geaboxs output to the rear diff. Where as i put in what it should be after you factor in the 1.1 multiplier. Hence why all my numbers are possibly out by that factor?

Still need to GPS set the vehicle speed input to the ECU. And also calibrate its output to the gauge. And make sure everything lines up with actual GPS recorded speed.

Justin may have the data on his laptop.....
He just chooses what to display as he is more interested in the engine is making power and is safe.

Yeah. The laptop and ECU will log all that data. But the Dyno itself doesnt. And the graph is a printout from the dyno software. Not the ecu or tuners laptop.

But i think they can be set if you know the ratios etc. Or you can select it from a list of already defined cars if your tuning a common model of car. Unfortuantly forester with sti driveline and 295 tyres isnt on the list of common vehicles haha.

Holy cow that should get up and boogie.. I may have stolen a few ideas from your build that will feature in the rebuild #2 of the bug..
