So with some help with couple guys from here (big thanks to C130flyer and Rolly1818 for answering all my questions) I think I'm done with my very first tune.

The car is an Evo IX on 93 octane. Mods are:
- TBE with test pipe
- ported exhaust mani, hotside, o2
- PTE 780 injectors
- Perrin intake
- full IC with pipes
- ECU based boost control set to around 25 psi

Let me what you guys think. Any suggestions, comments and advice is greatly welcome.





BTW how should I set my Low Octane Ignition Maps to?

 

its very smooth. but i doubt your finish... a stock map seems to be more agressive up top. .. did you reduce all that timing because of knock? and for low oct map i just copy and pay my hi oct and reduce thw whole thing by about 2-3*

 

The stock Evo IX map is couple degrees lower. But yea, if I add anymore timing anywhere I start getting knock... I thought it can take more timing as well.

I will make the changes to my low octane timing map.

 

umm also try reducing spool up timing you will see that it may spool up faster.. i did it yesterday and i hit full boost by 3000-32500 instead of 3500-3600 rpm.

 

and then just smooth out the map... alt+g and hit the jagged areas.

 

Do you mean take the 2.5k-3.5k (100-300 load) timing cells and drop them by couple degrees?

From what RPM range did you do your pull that you hit full boost by 3.2k? Tht pretty impressive.

 

Do some pulls and put them into Virtual Dyno Room. That will help you see any weird spots. Looks good!

 

+1. Run some logs though VDR and its looking pretty good.

 

Thanks everyone. I still want to squeeze another 10whp out of her. Since adding timing anywhere cause knock, I'm thinking about running more boost.... I think about 1 psi more should get my to my goal. Current VDR shows around 360 whp.

How much boost are some of you guys running on 93 pump?

If the car won't knock with more boost, does that mean I'm somewhat safe?

Thanks again.

 

looks pretty good, quick question does it usually spike to 26psi around 39xx and 47xx rpm? i noticed it had a 1 count of knock at 4781 and your timing was around 6 so it might be to much timing for the PSI. if i had a suggestion i would say maybe lean it out .1 from 3700 till redline.

nice job BTW!

 

got pics of mivec map? Spool could be slightly improved. May also have some more timing room up top. Otherwise looks good.

Def post up VDR.

 

I richened up couple spots (in the 4k range). I got rid of some of the knock, but still see about 1 and 2 counts in couple hundred RPMs. It is not always there, maybe in every other pull. I'm not too worried about it.

Here are 2 pulls from today (smoothing factor is only set to 4):



I will be getting gsc s1 cams from Aaron at English Racing, and hoping to get into the 380whp range.

Also learning about SD, so maybe this summer I will switch over to that.

 

not bad hp/tq numbers especially for minimal boltons!

 

+1 on the MIVEC table. It will prove to allow you a bit more power across the board if it is tuned correctly.

Your AFR is a little conservative. You can go as lean as 11.5-6 in the mid range (3750-6000 rpm) and still be ok on pump 93 depending on your altitude and Baro pressure.

Also, your ECU based boost can be used to control some of that taper at the end of the pull.

 

I really don't want to post my MIVEC map here. It is from a vendor I got a while back. If you have any suggestions on what to look for on it I can check it out and make the correct changes.

Since I have LS enabled, my AFR vary a little. Sometimes I'm leaner, sometimes I'm richer probably .4 give or take.

For the ECU boost, I already have the WG shut at 100 from around 6000 rpms IIRC (I don't have my ROM with me). The WG Actuator is the OEM one, but I preloaded it as much as possible. Any other suggestion on keep the boost on top?
