@ AndyCT9W. Which ROM are you using?

Any knock? Also what peak load are you hitting @ what RPM? Tapering to what load / RPM? This will tell us a little more about your tune..

Edit: Just saw it. ROM # 88770005. Is this ROM unique to the Evo IX wagon? I am unfamiliar with this ROM/ have never seen it. Usually, there is 3 high octane and 1 low in the Evo IX ROM's. I think, please correct me if i am wrong.

Have you ever thought of flashing a more common ROM #, possibly even one of the Tephra ROM's?

 

AndyCT9W,
I think someone more experience with how much timming can be run on the 4g63 can comment on the table's input, but there are two things that jump out at me ...the load/rpm axis of the surface, why is there "0" load or an 11000 clip? I think you could clip the rpm to ur rev limiter maybe and start the load at 10 to allow you for more tunning room in some areas that maybe needed.
The map could use some "massaging" as well... for example the spark jump at low rpm from 15 to 17 then back 15 between 60-80 load.

 

I'm also one of many who once searched for that guide without finding it a few years ago.

 

That spark jump is there for a reason.

It's associated with anti stall so if the motor starts to lose vac at low rpm the increasing timing helps bring it back.

 

Yes many of us use this in our timing maps. It's an idle catch up. It's also part of the stock timing map.

 

learned something new
thx

 

For the boost vs timing question, I've been down booth roads back and forth. If you can manage the heat and and remove intake restrictions, boost makes more power.

My computer crashed and I lost the pics. I'll have to put another one together. Let me compile my thoughts and whatever notes I can find.

 

nevermind

 

Good answer
Intake upgrade = convert to sd & remove maf housing
What size intake have you used?
Heat management: a larger intercooler would increase efficiency, some heat wraps all over... what else?

I'm looking forward to that guide too

 

[QUOTE=AndyCT9W;10803704]I'm after a bit of feedback on my 98RON (93 equiv) map. Intake, exhaust, fmic, stock turbo @ 23psi. How does this look? (Not tuned by me).

This is actually the STOCK table from the JDM GT rom! This was not tuned at all, it's 100% factory table.

 

Hey bro,

I'm from NZ as well, as far as I know in regards to MIVEC turbo engines, they can run more timing than Evo 8 and below, if you're boosting 23psi I'd assume you would be hitting over 280-300 load mark? Well I do anyway on my Evo 5 with evo 7 ecu.

Do some 3rd gear logs and upload them to this thread

 

In fact VIII usually takes more timing than IX. I think it's related to the IX having more VE up top (agressive cams+ mivec).

 

-Knock - 1-3 occasional counts.
-I haven't got load readings but I hit 21 psi @ 3.5k rpm, which creeps up to 22-23 psi @6.5/7k rpm and fuel cuts ( I will be sorting that out soon, if you know how to using ECU boost control flick me a PM).
-88770005 is unique to the wagon AFAIK, I've seen the option of flashing alternative ROMs (one of the options I explored when I was having trouble finding a good definition) but I haven't had the time to look much further into it personally. It is something I am interested in and will investigate when I can devote time to it.

Thanks for the feedback, I will look into that.

That is cool, really good to know.

 

Well...****... I just compared them and you are right. So is it fair to assume there is room for improvement?

Hey man, there are a fair few kiwis on here, I'm from Hamilton. My evo is on axle stands and missing a rear diff currently so I can't get a fresh log. I have one I did a while ago but I am having trouble uploading it (won't accept format), suggestions?

 

Hey Guys,

Here's my first map. It's FAR from fully tuned. I just spent some time scaling it to suit my car for right now. There were some goofy little sections where timing went up and down. I smoothed things out the best I could. I'm hoping to do some logging this weekend and actually make a few changes. Let me know if I did anything stupid.

Again, this is a stock Tephra V7 Evo 8 map scaled, interpolated, and smoothed out.
