I'm using the Megatune+Megalogviewer method but I can't figure a few things out. I don't see where I can edit my target AFR tables in Megalogviewer. I've tried to change them in the VE Analyzer but it gives me a "read only error."

Also, I can't seem to get the analyzer to agree with anything. Right now I'm running slightly lean, probably 16-16.5 under acceleration (without boost) and when I datalog and analyze it tries to lower the VE values even further when it clearly should be raising them.

My final problem is with my injectors. When I leave it at the (I assume stock) setting of 9.6 the car is too rich. When I imput my info into the calculator it produces 13.2 which chokes the engine and makes it undriveable. So right now I have the number set at 11.5 which is the best I've found so far.

Also, I'm doing some searching now but if anyone has an adjusted targets table that I can reference it would be great. I'm not sure where I should start raising values for boost.

Thanks!

Please post more information as to what else you have running, WB, what size the injectores, 1.8/1.6 etc...

IIRC the 1.6 stock fuel req is ~13.xx and the stock 1.8 is a bit less. You can access your AFR table through Megatune,. First you have to got the Lamda setting and turn the AFR table 1 for VE table tunning, if you havent done so. Then you can input the values you want to target.

I have a 97, 1.8, JRSC M45 w/600mm nose pulley, 320cc injectors.

Ok, will adjusting the tables in MT change them in Megalogviewer? I have the thread saved somewhere on how to convert the tables from volts to afr.

Yes once you save you msq in MT, then you open that same msq in MLV.

Also you might want to take a look at Tuner Studios Live VE analyzer

I really want to use TS but for whatever reason it won't load the Live Analyzer on my machine. I've been emailing Phil back and forth for the past few days trying to debug it.

Hmm, that weird. Try downloading the program and istall it again. I worked for me right away.

EDIT: be sure that TS is reading the firmware intalled on your MS. Theres a "how to sticky" in the MS section.

The ECU firmware is actually the problem. I've reinstalled (even clearing the registry) several times. When I create a new project and leave the ECU settings blank it will load fine but if I select (or let TS Auto Detect) the ecu it just sticks at the VE Analyze Live screen.

Any idea why megalogviewer and Megatune keep trying to turn my ve values way down whenever I try to street tune? Right now I'm tuning and keeping it out of boost with the ve tables from the 96-97 base map but it doesn't want to give it enough fuel.

Who built your MS?? If youre using Autotune, the modificaitons will be made accordingly to the AFR you target in the corresponding table. However given that youre having problems with firmware it could be something else.

D.dutton9512

It's the MSPNP system so DIY built it.

Give them a call and bitch

D.dutton9512

I might have to, I don't use their specific autotune feature cause it's supposedly not very good. That's why I use the megalogviewer analyzer.

Edit: Ok, I've changed the msns-extra file so that megatune's table now reads in AFR instead of volts. For some reason this didn't change the afr bins in megalogviewer. Where would I go to import my new table?

You have to set the AFR type in Calculated Fields.
