I actually logged my car during those dyno pulls I can post them up if you guys wouldn't mind taking a look.

Also I was looking at my AF from the summer when i got it tuned and it was actually a nice flat line and boost peaking at 20 and holding at 18 or so. So maybe it could be the weather?

 

Cold weather would make the boost go up, not down.

Yeah, also post up the logs.

 

Zip files should have my 5 evoscan logs if any of you guys can give me some feed back would be great.

In the summer with the same tune my AF was pretty much a straight line between 11.5 and 10.

just scanned my summer A/F and PSI chart

 

I just looked at your datalogs. Your timing is really jacked u from 3-5k. Up the boost to 22psi and raise that timing and your car will pull so much harder. Good luck.

 

I'm fairly sure the arf jump is due to the mivec change over, we see that a lot on 9's, it can be tuned out. If they are using 1.15 cf then that would be about
260whp on our dynodynamics.

If you can get the boot curve cleaned up and raised up to 21 - 22 psi with a tapper to 18-19 psi and clean up the afr's to the 10.5 -11.0 range you should be in good shape, plus add a good mivec map.

I have not looked at your log files yet so I cannot comment on the timing but I would shoot for 15* @ 7,000 & 17 @7,500 but then I'm used to 93 octane. Timing at peak torque will varry but around 4* if it can take it with an aggressive mivec map.

That should get you up to 280 ish on our dyno or 322 on that one.

 

^ Mine doesn't do that at all. I've actually never seen that on any of the IX's I'd logged back home either. Wierd.

 

If you look at his logs you will see alot of 0 and -2* timing from 3-5k. It looks like crap, no wonder the OP is low on torque.

 

Where these logs done on the dyno at the same time that you dynoed the car?

There is no AFR, but judging by the narrowband (please do not use this to tune your car), your running rich. That is why your car can run the advanced timing at the top end.

The timing at the low end is really poor. The car is in 0 to -1 timing from peak boost to about 500 rpm. That is why your power numbers are so poor. Running negative timing on an Evo destroys power. Your timing @ peak boost (3500-3750 rpm) should be around 4* timing on 93 octane and you should be able to increment the timing by 1* for every rpm increase.

Go back to your tuner and get your money back. And then head on over to Ecuflash and learn how to tune the car yourself. You can do it. I did.

 

Depends on the mivec map used and how the fuel map is setup, this one is more pronounced than what I am used to seeing. If you use a mivec map that drops the advance at 6,000 and try to use a fuel map that works well on a non mivec car you will get the afr step.

 

the internet is amazing... knowledge is power, and now you know you paid a good amount of money for a mediocre tune.

your torque is way too low because
1) your boost is way too low for a IX on 93 oct.
2) your running retarded timing
3) your mivec map is probably untouched

fix those things and you should easily gain more than 60ft-lbs at peak torque.

 

Yes, these logs were done at the same time as the 304HP graph and crazy A/F runs on the first post.

Definitely reading a lot now about tuning the ecu and stuff. Hopefully I'll get the hang of this stuff and finally be brave enough to start editing it on my own hehe.

 

look at it this way... you abt to have lots of free time so you can read up on it, test it out conservatively and if you screw up, i'll come over and fix it for you

 

When you look at it, even though the peak values aren't much, there is torque throughout the RPM.

I bet the car would be a blast to drive at 28psi and a decent AFR.

 

28psi!? isn't that a bit high?

 

Just alittle update on my whole issue. Got my mivec tuned and A/F stuff retuned and here are the new graphs.

blue is the new tq/hp and the green is the old.
