Nah the beers on me! I'm usually at the Wed night SJ meets.

Or just let me know the next track event your at...and don't hit my non-crash beam bumpers!

btw> Apex ..thanks for the post counts!

 

Yeah, id really like to see your graphs as well. With a full TBE most tuners can shift max torque to the left, yours shifted right. I imagine your plot looks more like a tuned VIII than a IX with bolt ons

 

12 hours and 60 pulls is ridiculous. Thats like 5 gal of gas.

 

I can see it taking awhile to get a good tune when you are trying to get great drivability and some part throttle and lower load/boost tuning going on..

Typically when I tune, I start with low boost, then step it up a few until I get to my target, this way I get a map tuned for nearly any boost condition I'd run into, then I tune part throttle for those different boost levels so I can revise the lower load lower RPM areas.. You can't completely eliminate knock simply because throttle inputs and fuel/timing shifts when it jumps load sites drastically, or lift/rattle, etc.. but It can take awhile.

I do agree with the "Area under the curve" Every 16g based plot I see that makes outstanding torque numbers generally has a giant spike for 500rpm and then drops off.. I'd rather not see that giant spike but a smooth and stable torque curve that doesn't fall off, makes for a more drivable, predictable, and fun car to race and drive every day.

That huge spike does nothing but make for a great peak number you can brag about.

In reality, you CAN produce these numbers on a completely stock car with only a boost controller, but it does depend heavily on fuel quality.

 

lol actually he said a whole tank. more like 12 gal.

blasted 9s.... I hate you.

 

How much power will this car lose if the AFR was richened to 11:1 from 11.5:1 and boost lowered from 23.5 psi to 22 psi?

Also, what was done to the timing map?

 

The higher the number the leaner, if your 11:1 to make it richer you'd go to 10.5:1

Just lowering boost should get things a bit richer if you don't shift your load cells.

 

This car is at 11.5:1, if I read correctly. How much hp will it lose if it is tuned to 11:1?
How much hp will it lose if the boost was dropped from 23.5 to 22 psi?

 

Ahh, sorry I misread it.. the AFR change should only hurt a few WHP.. lowering the boost a bit will hurt your torque, your WHP probably won't change much though, 5-10whp since the car rarely holds 23psi through redline, it tends to fall off after 5000rpm anyway..

At most I'd say 15-20whp, kinda sucks eh?

 

This is slightly OT, but would you elaborate on that comment Jack? How would lowering the boost not shift load cells? Does it have to do with charge temperature and the way that load is calculated?

 

That's a high reading mustang dyno almost the same as dynojet (on whp). As far as the gains, I'd say it's ok but not that good, On that high reading dyno you should be atleast at 300 whp.

In case you guys don't know the newer IXs are weaker (stock) than the IXs released in 05.

Evo ix stock on awd dynojet (released - June 06):
237.4 whp 234.7 wtq
248.0 whp 238.7 wtq

My IX dynoed 310.3 whp and 316.9 wtq tuned with just a catback (no MBC).

 

What are you smoking? Those gains are "not that good" with just a MBC and tune? What would you expect to gain with just a MBC and tune if over 70 whp and almost 45 lb ft of trq are "not that good"? Please share your tuning experience with us and give us an idea of what you could achieve.

 

You have an 03 evo?

 

That's what I thought, you have no idea. BTW, sorry to the OP for going OT, but some people post such utter crap.

 

Post is usless with out a chart, anyone can make a nice high number for 500 rpm.
