Tuned ROM: Galant VR4 Manual 7203

[TwinTurbo]

Hi Guys

Just thought to post my vr4-s rom which I tuned by myself, I just wonder your opinion and also accepting all comments recommendation and correction you will have

mapping made so far:

Fuel Map correction
Ignition Map correction
Open Loop Mode only

car runs on 98 High octane fuel, has Valbro, FMIC, Boost is 1.2-1.3 bars, depends on weather :)

[twisted32]

You seem to have a lot more timing advance from and around 160 load, 3500RPM than I can run with similar mods. Are you getting any knock?

[lateshow]

And you're running lean too. If I'd put that kind of fuel (11.3) I'd be getting over 12.X......

But your ignition is way too advanced, you must be getting lost of knock? Or do you have some kind of special engine that isn't so fond of knocking as mine is. I'm running the same boost and 6-8 less timing and still im knocking a little. What does you wideband sensor say about the mixture? What are you getting now in cruise mode? Or in full boost mode? :)

[Shtiv]

I've seen a heap of cars respond very differently to target fuel values. I've seen variances both ways of up to 0.9 from target values at high load.... I haven't opened the rom to see it (using a phone right now) just commenting on the comments

[TwinTurbo]

nope, I am getting 0 knock and I am checking it nearly once a week, the reason for that is a piping 2.5" - 3" and 600X300X76 FMIC installed on my machine

Wideband shows the same numbers that I have in map.


and I am running stock internals, TD03 is not enough to handle 1.3Bar so I am planning to replace them with TD04 from WRX

I will check acceleration and 1/4 mile time once new clutch will be delivered and installed and will post results here.

[lateshow]

Wow, you must be getting lots of power then!!!! Nice to hear that your wideband gives same numbers! I'm planning to get miself a water/methanol injection to get similiar results.

[TwinTurbo]

come on guys, I dont believe that I am the only one running on such ignition with a stock internals, piping, FMIC and 0 knock, during a tuning I had a 4-5 knock once but was reduced with retarding the timing by 1

I will try to upload a ignition maps that I was running with stock intecooler.

we do not have dyno here and I can not tell you exact power and I can not even test 402, but I can tell you that car now runs much better then stock evo.

[Kenneth]

My Ignition map. I get the odd knock count, but not much. I did have to take some out of the 2500-4000 region around 100% load but I think my turbo is leaking oil into the intake which wont help the octane rating.
It could do with a bit of work probably, but hey. My last set of logs basically told me I needed to take some timing out at a few points so I did :P

45003

[TwinTurbo]

can you pst fuel maps as well ?

[lateshow]

Im doing generally few steps more than Kenneth is and getting some knock ~5. Not every time

[SmartBOOST]

Twinturbos maps was tuned by me. The Car runs Great with no knocks. But that isn't final config. We're moving forward for better config.
Keneth can u post your fuel maps to compare.

[TwinTurbo]

heh, my friend is here too :)


yep, its not a finel config and once nw clutch is delivered we will start to work again, going to have more aggresive timing on high RPM-s, approx after 4.5-5K, where turbo is abit "dying" due to its small size, for example I am getting pick boost of 1.4 bar at 4.5K RPM and the its droping to 1.1-1 bar till 6.5 RMP. bad point for us is that we are going a road tuning (no dyno here) and the only thing that we are counting on is our feelings and evoscan log

once new configuration is done I will post ROM and EvoScan log here

[lateshow]

TwinTurbo: I'm eager to see your logs :) It seems that a proper cooler means a lot. I have a 450x300 and that isnt clearly enough. I still can't believe that one need a 3" piping for cooler.........

[TwinTurbo]

not a problem, alway glad to help :)

here it is, also I will include ROM that was tuned with standard piping and 600X300X75 2.5" inlet/outlet FMIC Only, you will be surprised by comparing old and new timing, fuel maps was not touched, here is a full specs that I am running with.

2.5"-3" piping
600X300X76 FMIC
Valbro 255 LPH FUel Pump
Boost Cntroller Blitz, Boost set on 1.3-.1.4Bar but its too much I think because coost is droping after 5K RPM and holds 1-1.1 bar only
3" Fujistubo exhaust


no downpipe installed yet and I am expecting a big difference with it.


one thing that I would like to ask you is to help me with setting up 2 byte Load in evoscan, if anyone knows how to, because all this tuning was made with Load Calculated.

[lateshow]

@ MUT 00 and 01 FD08 and FD09 with your ROM should do the trick, is she auto or manual? Your load calculated shows very little values......like boost 0.9 bar :D And the right formula in evoscan for 2 byte load MUT is 0,2326x

[TwinTurbo]

yes, it shows a little values, thats why I wonder that ROM config is not a final one

Mine is manual


Lauri, if you have already configred XML file for EVOScan with correct MUT 2 Byte Load, can you please send it to me

Thanks in advance

[TwinTurbo]

ok guys

Yesterday tested and tuned kenneth's ROM on my car, and result stuned us :)


here is a tuned rom itself, boost is at 1.2-1.3 bar.

enjoy advanced timings :)


tuning was performed on a road, no dyno available yet, after tuning the car we had some rolling starts with BMW 135i TwinTurbo from 1st gear till 4th, and result shocked us more :) we were running side-by-side till 150-160, after, 135i was going into lead for couple of metters due to its 6 gear gearbox, as found out later 135i has bitten E36 M4 SMG-3 in rolling starts, so waiting for an oportunity to bit e46 M3 on a rolling start :)

mods comming soon:

Ceramic clutch
custom downpipe


Biggest thank you to my friend SMARTBoost (nick on clubvr4 forum) who tuned my car :)


later will post a video and evoscan log



anyone interesting with such a performance on stock turbos ? PM :)

[Kenneth]

Thanks for posting the rom up :)
When I am at home ill take a look at it.

Might even flash it to one of my ECUs and see how it goes in my car ;)

Thanks again for sharing.

Oh, and I may have some progress on the launch control... Should have a better answer by the end of the week.

[TwinTurbo]

thanks Kenneth

waiting for your answer on that and once again thanks for you afford :)

[TwinTurbo]

As promised, here is a log file and virtual dyno test run :)

Just took a look at TwinTurbo:s Evoscan file. For starters 2-byte load peaks at 200 and goes down to 140 which suggests that boost is around 1 bar and drops as usual. Judging from the value of ignition advance it is reading such columns that it is doing about 0,6 -0,7 bar pressure @ 6000 rpm where it appears to have the full power. So if your meter says you're doing 1,2-1,3 bar the metercan show wrong? Other thing: Injector duty % tops at ~72%, which suggests you have ~300 hp from the flywheel. I did dyno analysis on evoscan and it says 300hp/446Nm for max values (3rd gear, 1,407 for 3rd gear. 4,11 total, 1500 kg car, 100 kg load on car, 65,3 cm wheel diameter and so on.... Every car I have tuned has shown that 1.2 bar boost pressure requires ~220 load.

[TwinTurbo]

its a road tuning so engine load on road tuning are different from dyno, sometimes you are running on uphill and load goes above 200 on 4th gear, on downhill you get max 180 on same boost, so can not say that 200 load is 1 bar exactly when you are doing road tuning. from my experience it was so, we tuned evo III 2 days ago and it was showing 240 load on 1bat boost.

[Shtiv]

load = airflow, boost = air pressure at which point factors like turbo efficiency and heat and therefore density etc come into play. My point, ignoring different cars, 2 vr-4's with even the same turbos might make diffferent power at the same %load point.

That timing is more than I have seen working on one of these without knock, and I 've seen a lot of them, if it's not knocking you're doing something very right (or you have really good fuel or something)

[lateshow]

Yes, if it can use that much advance it is good. But a friend tried to calculate the power of that log with dynovision and I tried evoscan, using 3rd gear we both came up with roughly 300 hp.....

AND


Bigger airflow means more potential power, bigger pressure doesn't mean that.....

[Shtiv]

but if one uses more boost to get the same airflow it's less efficient and probably making less power....

[lateshow]

Yes, after ATF flush I'm getting much less knock and yesterday tried the same on the motorway (3rd gear from 50 kph->) Sadly, I was logging too many items and the log got ****ty so I ca't calculate anything, but seems to go use about the same advance. Boost peaks at 1.3 bar and load peaks at roughly 230. 0 knock. Intercooler makes a big difference!

[TwinTurbo]

Lauri

you used the same timing advance that I have ?

I just wonder why I am not getting more then 200 load, strange, my boost pick is 1.3-1.4 bars also, can you please make a log and post it, also would be great to see you fuel and timing maps
