anyone of you have a basemap for utec turboxs 600cc injector? i'm driving a 350z and my mods are vortech 3.12 pulley and 34 tooth, 5/16 MD spacer, test pipes kinetix, XO2 exhaust, walbrlo, so if any of you guys can send me a basemap i'll appreciate, my email is wenlipai@gmail.com thanks

 

Go to turboxs site and download the 550cc map and adjust only the 0% column in the Fuel tables. It will get you to the shop to be tuned. Just don't go into boost. Or you can just trailer it that's what I had to do.

 

hi thanks, i did went to turboxs web but didn't found the download site, got any link? thanks

 

Here you go, http://www.turboxs.com/utec350zupdate.htm

 

thanks

 

By how much should the user adjust the 0% collumn? For some reason my a/f ratio is very rich at idle.

BTw sorry for bumping up an old thread

 

what injector do you have and what is are the numbers you have on your 0% column?

 

I have installed DW injectors rated at 600cc. The fuel pump has been upgraded to a walbro 255lph and the fuel system converted to return-style with fuel pessure dialed in at 50psi.

I have not adjusted the numbers in the 0% column yet but I just wanted to know what is acceptable. The base map that I am using is the one from Turboxs for the T-netics kit with 550cc. Base a/f on idle according to my wideband is around low 11's.
Any help would greatly be appreciated.

 

I asked you what value you have on your 0% and you had to make me find it the hard way.... The T'netics has a -2 to -5 on the 0 column which is whay RICH!!! try -12 and see how it respond with your DW 600cc... I think the APS 550cc is better than the TN base map.

 

Sorry about that but thanks for the help.
So the way I understand it is to adjust the variables to around -12 in the 0% column but how far down? The threshold is set to 2000rpm. Also you state it would be a better idea to upload the APS 550cc map with parameters and then adjust the 0% column? Or should I leave the 0% column the way it is with the APS 550cc map?
The values in the APS 550cc map in the 0% column are -19 to -17 starting with -19.

 

I say start with the APS and go from there... You cant really do much with the 0 column because that is being used in close loop. The ECU will always try to do its own scaling via 02 sensor unless the injector is just way big and that is why you need to setup your 0% right. -2 with a DW600cc is just asking for it, heck I have -5 with my old DW440cc which is really just a 400cc.

 

Thanks for the advice. I will then upload the APS 550cc map and parameters and see what the result is. My goal is just to be able to drive the vehicle to get it tuned (2 hours away)

 

just keep changing the #'s til you get the AFR you want. Making a rough in tune on a UTEC is simple for a supercharger since you only use like 30 cells out of the entire map


EVery car is different, so absolute #'s arent that important.

 

Thanks for the advice. However my vehicle is not supercharged. I just need a tune to get to the dyno.

 

Ya, then just use copy thru ignition timing (100) and run -12 in the 0% column for the fuel and the car should run basically stock (assuming your param file is setup properly)

Heck with 600s, you can run the stock ECU, and as long as you dont tip into the gas too fast, it will run stoich just fine.

 

So would it be better to run the t-netics map and adjust the 0% column to -12 all the way down or just run the APS 550cc map and leave it as it? Also anything to know about the parameters meaning would it be fine to just upload the ones turboxs provides and leave them as is ?

Right now on stock ecu the a/f is far from stoich.
