I've started monitoring the CEL on the MaftPro, how can I tell which CEL # maps to which cell on the following VE table?

VE table

I've noticed something weird where the CEL value on the MaftPro usually is stuck on 0 but will bounce around to some other values (41, 51, etc...) but then returns right back to 0... what's going on here? Shouldn't it always match a cell value on the above table?

I'm looking to decrease fuel at around 43 MAP(KPA) for cruising and increase fuel at around 30 MAP(KPA) for reving in neutral. Currently I'm running lean in neutral reving and way rich in gear while cruising. Bob, maybe you can release a new VE table for us that would address this problem? It sounds like multiple users are experiencing the same lean/rich conditions.

I'm thinking of just bumping up the fuel for lower MAP values a little bit (i.e. +1 on each value in the bottom 2 rows) to richen it up a bit during neutral revs.

Please offer any advice if you have it.

-chris

the lc-1 has 2 analog outputs, one is a narrowband converted signal, i think you used that one to connect to the maftpro

thats what i used. its the yellow wire if your fimiliar with the lc-1. whats the most common idle issue. i beleive i have Ver.4.8X. most of the info i found searching talks about VE2. which i cannot find much info on adjusting this or how it works. my idle goes really rich to really lean spontanously. would i use temp compensation for this? thanks guys.

I have the same problem with the VE cell variable thing, its always at 0

use the brown like i said in my other post.

venik · 04-25-2008, 05:53 PM

how do you know what cell is what? ie what VE cell is 67, or 53, or 37..etc?

Cel is 0 when the Pro is not 'mostly' using one cell.... The idea is to make a long log with tunerpro, export it as a CSV file and use Excel to remove the data where the pro is half way between cells.

cell 1 is the lower left, counting up as you go across. cell 16 is the second row, first column.

the BIN I posted for 5.03 has this.

Storm Strike · 04-26-2008, 08:26 AM

So, updated my Pro to 5.03 yesterday and uploaded the stealth5.03 file TB posted. Running larger injectors than TB is (Evo injectors flowing ~620), so I tweaked the mainscale to about -26 and fiddled with the low range 400-1200 to get the hot idle back where I wanted it. Was able to boost to 15psi in 3rd gear without knock for the first time in a long while.

Still need to get the .xdf file for 5.03 to update TunerPro. How do you view the VE table in real time while driving?

you need the proper xdf, make sure the BIN iin tunerpro matches whats in the Pro (download the BIN from the unit and Save_As)

start the ALDL logging, and click the "Enable ALDL Data Tracing" button. When the VE table is on the screen the cells in use will be yellow.
