the vehicles here in are mostly JDM. does anyone have a solution?

Thank You!

Hey, this might sound stupid but I'm curious as to what generated the following images


and


Were these generated with EvoScan? If so, how? what settings were selected?

Also, what inputs would you suggest to start initial logging while tuning? (RPM, TPS, etc)

I think he was using the dataloglab program for those although if I am wrong someone please tell us how to do this as it looks to make things much simpler

A Few questions, probably been answered already but theres 43 pages and Ive already read through it twice :P

How do you configure the ECU to read 2byte load? cause right now im logging under loadcalc.

And also, just curious as to what you guys log? Im currently logging,
- Knock Sum
- Engine RPM
- Load Calc
- Boost(MDP)
- Speed
- AFR Map

Yet, all my Boost levels are reading waaaaaaaaaay too high. do I need to reconfigure something to make it ready accurately? its saying like 40psi and like 18psi at idle.

that program is called Logworks. It comes with the innovate WB 02's. It also has a plug-in, so it can log everything that evoscan can, though logworks.

Yea, I figured that much out. Im using EvoScan and ECU Flash right now but some of the data seems off and Im curious as to how I can get it to use 2byte load.

and if i need to calibrate boost...its reading like 40+psi in evoscan and Im like "wtf"

Do you have a JDM/EVO X map sensor?

Have you switched the readings in evoscan to think it is a 3/4bar sensor? sounds like it is reporting as one.

does this apply to the X as well or should that just be seperate? I would guess rules are rules right?

I was thinking the same thing. I would assume the theories still apply.
