Honestly with open source tuning you never know who had their hand in that tune after the fact .. Sucks but thats the bottom line . Idk if you personally took the car there and got that tune thats different I say

 

This thread needs to stay on track. Fully tuned timing maps. Not here is a map, vendor defend, vendor attack, etc.

Next derailment like this in the thread there will be points awarded.

Please keep it clean and on topic.

 

Migs you forgot #1115 & 1116

 

Thanks. Further cleaned.

 

Is this on a 4g63 or what?

 

4g94

Retuning it at the moment.
I didn't realize my EGR went bad on me (I'm assuming it was stuck open).

After I sold my 272 camshaft it still loped during idle
I thought it was my latencies, but after I installed an EGR block off plate it idles and starts normal again

 

So I decided I would get my feet wet and start tuning a little bit before I have money for injectors and a professional e85 tune... read up on how to tune an evo and merlins ecuflash guide...

attached is a jpeg of the log in excel and a jpeg of the new timing map... let me know what you think of the timing map before i go blow myself up!

05 MR with catless TBE, drop in filter, walbro, licp, mbc set to 21 psi

not much knock on the stock tune...

logged on a flat road and was at about 270-290hp and 240-260 tq on VD (all 3 logs were different on the EXACT same section of road... but they were one after another within the same 5 minute time period so that could be why?)

 

You're running quite a bit richer than you need to Taylor, you can lean it out to mid-low 11's; no reason to see 10's at any time. I would start with getting the fuel at least out of the 10's before playing around with timing, as just leaning it out will add power.

 

thanks raptord! so I should tune the AFRs before messing with timing?

I figured it would be best to fix the AFRs first but I had read that it's best to do the afrs last...but I see why in this case its better to do the AFRs first since they are so damn rich..

I've been using excel to calculate the AFRs. I think I'm gonna try and figure out how to use logworks. When I used the maptracer in evoscan it didn't really work well

Also: when I try to log mut load 2byte and load 1 byte it doesnt work... is it ok that I'm only logging calculated load?

Should I ditch the timing changes and try flashing the car with just the AFRs I posted?

 

Generally you should adjust timing first, and then A/F later. With the stock intercooler you will probably get heat soaked fairly quickly if you're doing a bunch of back to back pulls.

I log calculated load, and don't really have much trouble. Make sure that you are changing the values to the left and to the right of what evoscan logs. That way you will get more consistent results if you're fluctuating between load cells.

Make sure that when you are doing your pulls, that you do them on the same stretch of road preferably going the same direction to aid consistency. You want to make sure that you're changes are related to your tune not the road.

I like to do like three or four back to back pulls to make sure that even if the intercooler is getting heat soaked, it's not knocking like crazy.

 

Yes, usually you do timing first, but since your AFR's are so far out of the "normal" range I'd recommend getting them at least in the ballpark before messing with other things.

1Byte load is only available if you're using a TephraMod, and to use 2Byte you need to make changes to your MUT table first, so that's why they aren't working. IIRC 2Byte load would be more accurate than calculated load, so you might want to configure 2Byte load and see if there's any discrepancy between 2Byte and loadcalc.

Also, I forgot to mention this in my first reply to you, but you're logging more things than you need to in evoscan, which is slowing down the number of samples per second you're getting. Only log what you need.

 

One thing that surpises me with these maps is the scaling and the power output of these cars. I'm hitting 310 load and my power output I would assume is far lower. To see some of these maps that haven't been rescaled has me wondering if there is an issue with my car, the cars are running off their maps by quite abit, aren't making the hp claimed, or I'm really under estimating the power output of my car. Maybe I need to head to a dyno, as the virtual dyno has me only making 205kw.

 

^ Could be due to a boost leak.

 

I've tested for boost leaks, none that I can find.

 

Timing should be done after fuel as the AFR affects the flame front speed and the flame front speed determines the timing.
