couple of questions guys

1. I downloaded 96531706-TephraMod-phenem-sd.zip. I noticed the SD Map does not have 1:1 relationship. Is this correct, page 1 of thread says start with 1:1.
Should I leave it as is?



2. My current ROM's MAF scaling(left image) has been changed from stock, not sure why, was like this since I've owned car. Perrin Intake.

Should I copy mine over or use default settings in rom?



Other then, that. I'm gonna give it a Flash as seen what happens.
I've copied over all other required tables from my ROM.

I'll be using Fuel temp rather then IAT sensor.

Any suggestions are greatly appreciated.

START by using the 1:1 relationship OR use the default settings OR use the ones I have posted but DO NOT RELY ON THEM TO BE CORRECT FOR YOUR CAR! Every car is different. Follow the rest of the steps, tune your car correctly and carefully.

What about MAF values, copy mine or use default?

I copied mine to help the conversion process go smoother but really it's not very necessary to if you are going to be tuning from scratch.

thanks for your help. appreciate it.

I'm gonna flash it, unplug the maf sensor and fire her up.

? for dialing in cruise.
@2500 or 3000 cruise LTFT-Mid stays @ 12.5
so,
Am I to raise RPM-VE above 100% or lower MAP VE.
If MAP VE then @ what loads.

I'm trying to follow this:

LTFT is a bit negative, lower the appropriate RPM VE and/or raise your MAP VE values a few % at a time to bring them back in line. If the LTFT is positive, raise RPM VE and/or lower MAP VE.

I'm starting from the maps that came with ROM posted above.

thanks

. If the ltft is positive, I would increase map VE, you have to calculate kpa using your map sensor.

I would start with map ve 1:1 at that point you will probably find your rpm ve high. I found multiplying out the two tables into a 3d table helped dial everything in.

Can you give me an example of how to begin creating 3d map
X and y axis values,etc.
I'm assuming i will need load to kpa translation

Thanks for your help

And

for tuning the sd i'd recommend putting in open loop full time the adjusted the ve table to get the desired afr's then go from there

This and by using livemapping for VE tuning it is very quick operation.

thanks guys,

@ this point it idles and starts fine, however. I noticed it WB goes reeeaaal lean when I start roll into boost. I backed off right a way.

I'd like to address this, what's the remedy?

Should I focus on trims 1st and then lean issue?

i have been having some problems setting this up for the past week. I have my cruise, amazing. car run extremely smooth during cruise and a/f is dialed in. But my problem is. the second the car sees boost, it go VERY RICH. at only 4psi it is seeing loads of around 240-250? i have read a number of posts saying playing with the VE and RPM tables will effect load, but, i have taken away and add on the VE tables and i still get the same effect. could some1 give me some help?

Did you lower your Mapve at the point of going rich? What load were you hitting before the switch to SD in that location, and did you change injectors inbetween any of this?
