just open it in open office, drag rpm column to first then use x-y graph for selected WOT length. log analysis is first thing to be able to do.

do you get access to turbo dynamics with esl too? i log boost error and dynamics too as there was no point targeting a unachievable value early on and winding up integrals.

its worth doing a pull with boost solenoid bypassed to check see if wastegate opening pressure is sensible, i had to start again after checking and adjusting mine.

You can see the boost in graphical view in virtual Dyno. Or log works if using a innovate wideband (with map input)

Works very well with csv files from alcatek logs, I'm sure it'll work with esl too.

I'd strongly recommend starting mapping at wastegate boost and slowly working up from there. You don't want it to det on part throttle or transitions.

SiHethers, its saturday morning and a beer is in flow, not sure what you mean, simple terms please lol

SiHethers

The load areas below target boost, because at part throttle, boost and hence load will be lower. Similarly when you suddenly change throttle from closed to open (transition, on gear change for example) if the lower load cells you access are not properly mapped you might get fuelling or detonation problems. You shouldn't just focus on mapping peak boost areas of the map.
If you connect the turbo nipple pressure source directly to the wastegate you will run the lowest boost possible, usually about 0.6 bar on standard turbos.

O.k bud, cheers for the advice

safe to say i wont be trying this at home.

good luck ,sorry i cant give you any advice

Did you adjust boost ceiling and the turbo dynamics as I can't find info of what it does or where to adjust it to don't want to guess as no info in manual

The Rig

iTrader: (13)

I didnt adjust the boost ceiling or turbo dynamics, think thats for the pro`s to fiddle with lol, would be intrigued to know what the adjustments do tho.

Jaysz

Same
Did email andy but didn't say what settings do or how to adjust

Very interesting thread and one I will be following. Just goes to show how very complex mapping is but at the same time very interesting indeed. I'm glad to see a few non pro's giving this a go albeit with mixed results. I'm sure with many many years of practice that self mappers could become semi pro and have a great map which works well for their car.
I look forward to the day when I eventually get my ESL so I can see what it's really all about,I will however be reading the manual 2 or 3 times before I tinker with the base map. It's great to see so many pros on here willing to offer very good support and advice
Good luck @The Rig I look forward to reading more

I learnt ALOT from the ESL manual, Andy's help and playing with all the ESL software. I think if you go slowly, self tuning is a very rewarding and fun thing to get into! With its risks of course!

Cheers bud, my mapping is pretty much finished now, car performs very well, pulls your head back in 2nd/3rd gear and so much better than when mapped by the "professional" that mapped it last time so all in all, im well happy, had lots of help from the guys on here and Andy so its not been all my own knowledge as such but ive had understand it all and now I do, well, the car goes very well.

How much has it cost to map it yourself rig??

The Rig

iTrader: (13)

It cost me the ESL board and cable package and I also bought a wideband which was £140 .

Considering you need to pay a mapper each time a change is required having the cable yourself pays for itself in the long run (if you plan on extra mods and tweaks of course)

Heres my Final map guys so just thought id post it up to show the end of my efforts lol.

Top 2 boxes are on the left AFR (from about column 35 the wideband goes out of sync so if it reads 10.4 its 11.4 etc) and on the right is knock control with the red -0.50 in it.

Not been on the rollers but in road terms it drives excellent, pulls well, like a train and well, drives like it should :-) . Open to criticism so dont be shy ha ha but like i say, it drives well so if anything is amiss, i cant tell :-)

cheers

So what does your wideband say at wot from 3600- 6500?

Just curious really as I'm still at 11.2 ish currently.

The ign looks very similar to mine but I have more resolution at higher loads than the lower ones.

What would be good would be to see a trace over the map after a power run, just to see where you are running, or a log file.

I got mine something like and left it as I have been sorting out brakes and handling of late. Will be back on it sometime soon and I think I can run a bit leaner than I am at present. Somewhere near 11.5 should do it but to be fair it drives fine as it is and I don't feel the need for eeking out the last bit of power from my setup. A safe and driveable car is my aim. I think 300hp is plenty in a type r on B road blasts.

Just to add a bit to the knock control map. I recently fitted my decat downpipe and now I get it pulling timing a little as I hit full boost earlier. I got 2 cells at -0.75 in the knock control map. I corrected these and it seems fine all round with no det.

Its nice to see it working as it should.

ha ha i might aswell be reading Chinese for the help i can give, i wish i could remap my Impreza

My wot wideband readings are 1 unit higher than the actual AFR table, so at 3600 my table reads 11.5 but AFR on wideband is about 12.3 and at 6500 wideband reads 11.4 whereas the table is 10.2. Close enough for me lol. i dont want to go any richer as i found when i did, it felt slower, i had wideband at around 10.8 and it felt worse so stuck to the 11.4 at WOT as i tested 11.8 - 12 at WOT and had more DET.

Yeah a trace would be good, will get one posted up soon

Glad you sorted your knock control map out, ive reduced timing in the area affected on mine and got it down from a -2.00 to the current -0.50 so thats good enough for me, its at 2600 rpm as well at 3/4 throttle so maybe its a dodgy engine mount or something as it happens when im poodling about by the looks of it at 3/4 throttle low rpm.



And JayGSI, the people who can read chinese had to learn it so if they can, we can ha ha :-)
