For what it's worth, the tool on the link below shows a HP difference of about 5% from 50 to 90 degrees. Or a "300" hp motor makes 309.3 at 50 degrees and 295.8 at 90 degrees. That doesn't sound right... I would've guessed the difference would be larger.

On a n/a car yes but on a forced induction car after several runs you start to get heatsoak which makes a more drastic difference I would think

That sounds a little off. On a hot day with bad stock intercoolers your power level will be significantly reduced.

So Jake, anything new or almost finished or in the middle of testing we should know about?

[Jake@JHM]

Stage 1 has had a ton of revisions this week and last week, so its getting CLOSE!

[RoguesGambit]

I hear ya, damn!

What happened?

[Jake@JHM]

I hear ya, damn!

What happened?

Calibrator had time to crank out a bunch of reversions making sure that the tuning is 100% perfect

[RoguesGambit]

Nice, anything else in the works? Thinking about messing around and getting an Intake for the hell of it, who do you recommend or do you have one in development?

I made my own for now. We may work on an intake for those who have FMICs though!

Sweet Odin's Raven! .... Just got a pressing break in the JHM stage 1 tune....

Well, unfortunately that tune will not be available for the market since we did that using 220 octane.

[RoguesGambit]

Nice

Gotta get the FI exhaust and FMIC after I get my summer toy

Indeed!

Just a matter of what to get, but that's for a chatterbox thread

You need to get the JHM/FI cat back, the JHM DP-Y and the JHM FMIC!

Indeed. See the attached dyno for a Dyno comparison of stock vs JHM DPY +FMIC+C/B

That's after the roadster, unless I work on that right away xD

[CVTwhatadumidea]

Dear God! I want this tune! When!?!?!

[Jake@JHM]

Dear God! I want this tune! When!?!?!

Soon, young grass hopper! We are getting closer and closer every day!

[CVTwhatadumidea]

1 month, two months?

[Jake@JHM]

1 month, two months?

We are aiming for that range or sooner if possible

[Audibot]

I'm staying tuned... this looks quite promising. I was a bit mislead by the dyno chart saying "91" in the corner until it was pointed out it was 220. Where do you even get that?!

Yup, its a blend of 91oct and jet fuel with a hint of garlic.

This tune sounds super promising but I'm a little disappointed that the nearest dealer to me is like a 4 hour drive :( Damn you for being so big Texas!

We sell cables too

[tehuberduber]

We sell cables too

Think the cable will cost less than a tank of gas though? It's ok Houston has great Indian food and I'll be hauling major ass on my way back to Austin :)

Well a tank of gas + the cost of labor the shop charges to install the tune will most likely be cheaper than the cable.

[swaggerwagon]

You guys have any plans for expanding in NC? It'd be nice to see some more NC dealers, or even my guy (EUROWISE) become a dealer for you.

[Jake@JHM]

Just about any qualified shop that wants to become a flashing dealer will be able to. If you know shops that are interested, have them contact us!

What hardware is gonna be needed for the stage 2 tune ?

[Jake@JHM]

What hardware is gonna be needed for the stage 2 tune ?

Turbo back exhaust - preferably 3" or our 3" to dual 2.5"
FMIC or upgraded SMICs

[mec]

Do you have dimensions for the DPY? or blueprints? I want to figure out where I can stick that exhaust dump

It was design to bolt straight up to the stock cat. I cannot supply blueprints but I can send you a pic.

send me all the dirty pics you can!

I'm thinking i'm gonna have to just get it and install it then revisit the exhaust dump idea because its so hard to tell what will fit without it being installed.

Yurp. You will also need a test pipe that will swoop down the stock location so the DP-Y fits everything else properly. I would recommend installing the cat back, then the DP- Y and use something to hold the DP-Y in place so you can make the TP in the right place.

[mec]

Well my existing DP is supposed to bolt into the regular location, issue is that I have a vband, so i wil need to chop off the DPY flange and weld the V band onto the DPY.

ORR get an extra flange and bolt it up.
