Evan, can you post your MAP VE table? Do you have values above 150 in the top row right hand side? Can you post a log including MAP and load as this happens?

03whitegsr, at your altitude you'll definitely need to use baro compensated load to set this up. At sea level you could get away with it.

 

is Loadcalc in evoscan compensated load? I am not sure which ones are which.

 

Thanks cossie, you always been helpful!

 

No probs mate.

 

Here is the Map VE right hand side Load %.
6.98438
13.9688
23.0019
39.0194
54.0125
89.9587
130.002
310.013

Here is a pic of a log of when I try to hit boost and what it does.
I have many logs, long ones too. I can email them to you if you would like.

I think the big turbo plays a role here, however driving around out of boost is better than with the MAF lol.




Thanks so much!!!!

If your STFT is +25, then its too lean. This is likely the problem. What MAP sensor are you running, and please post your VE tables. If you have an EvoScan log, please post it.

 

Your load certainly seems to be going up with boost. TPS looks wrong.

It may well be that it will go rich when you go properly open loop, I think here you were probably on the edge if not still in closed loop, your bottom row of the MAP VE table at 90 and 130 load may need to increase. I can see why you wouldn't want to push through a lean area if you think it will just go leaner coming onto boost. Perhaps you could state what load you're going to need at 200kPa (1 bar of boost or 14.5PSI) and also the load you usually hit in the midrange so that you can fill out the VE tables if you haven't already done so.

Can you attach a log from your MAF sensor which includes at least 2 byte load, RPM and MAP? I don't want to make the US turn metric, but it works much nicer if you display MAP in kPa and absolute pressure since at least on stock turbos they're near to 1:1.

 

Im using the JDM 3 bar. Im sure its working well as it follows my boost gage exactly in psi.

I posted a log above.

I can email you many logs, (they are to big to post.) Whats your email? Thanks so much guys!

I wonder what could be wrong with my TPS? Car has been in a box and now running again, new motor, turbo kit ect. ect.

Thats what I think too, as far as switching to open loop. I do know I would hit 379load at 17 psi with the MAF maxed out. Would playing with when open loop switches make any difference?

I dont have any logs with the map on running MAF but I will get some if you would like...

I think this car will pull similar loads to Mellon's big turbo car.

 

Are you logging with the baudrate in evoscan set to 62500 but the baudrate in your rom at the stock 15625, as i've had similar tps readings when doing that.

 

Thanks, I do have it at the stock 15625...

 

quick question, how do you get evoscan to log KPA not psig?

 

edit the scaling.

go to jdm map, and change it to 1.334*x and then change the psig to KPa

 

If you're hitting 380 load with only 17 PSI (217kPa) (do you really mean only 17 PSI as whilst the big turbos are efficient it doesn't sound right to me) then you'll need a wildly different VE table to the stock turbo guys, so the MAF based log of mixed driving including full throttle, cruise, idle, will be essential to setup your VE.

 

John.

I put my car back onto the maf sensor last week, as I couldn't sort out that "popping issue" and I also had to change my injectors as someone bought the ones I was using lol.

Anyway tomorrow I have a 400 mile round trip to do (swapping clutch finally and getting a new gearbox ).

If I do a single log (as in all the way there) which will cover all types of driving (no doubt), should that be good enough for you to beable to sus out the correct settings for my car ?

I messed about with different logs and settings for about 4 days or so, and in the end I made it worse than you did with 3 crap logs I sent lol.
