Tuning zetec ALpha-n, MS1 with WB and tech edge controller

[RobC]

Having tried to get the mixture right ... I am have a few question (I have done a search but...) Anyway...

Dum questions possibly sorry if they are...

I want to use the WB lambda throughout the curve, This needs to be set to closed loop or so I am told... do I just set TPS and KPa to zero in the open loop dialog box in V2.25 (megatune) ?

Whilst looking at this do I also need to alter the lambda sensor targets? and also set the taget tables to VE1?

Very confused... and I havn't yet figured out why mstweak isn;t working but thats another frustration which I'll get to later ...

Cheers for any help reading the tuning section, but the more I understand the more puzzled I am becoming...

As far as Mstweak. First make sure that you have the most up to date version. Then go into the settings in MStweak, then set your "Ego crossover to 2.5 volts". Also you will need to find where your Megatune is installed (which directory on the pc) find a file called "car 1" go into there and find a file called "mtCfg" then open "Settings" go down the list and find "Non liniar Techedge" and change the word "unset" to "set". Also type "unset" infront of you "narrow_band_ ego.



Good luk i hope this is what you needed!!!

Just in case.... (re MsTweak no worky!)

I could not get MS-Tweak working on Saturday!

To cut a long story short, I found that the datalogs from the recently loaded 029b firmware add a line to the start of my log looking something like this:- 'MSNS_e 029b'.

Once I deleted this line it worked fine....

Hope this helps you or someone else...

ps be sure to use notepad for editing your xls files....

Yo, i have not ran with the 029 code yet. But i hope to be within a wk. Also i have been having problems with my "REQ Fuel" Cubic inchs, or in yor case CC's. It always resets to 350 cui, and my lbs per hour always resets to 42 lbsers. So if no-one can figure this out i bet i can tune with it like that!

[milesinfront]

Don't worry about it.... That window is just a calculator and those figures are just the defaults. You enter the correct values then press ok and 'hey presto!' your required fuel value appears in it's window.... You never need to go back there again.... (unless you change your injectors etc...)

Cool so i thouht that my engine ran a little different because of this. But our right the required fuel never changes!!
