Trouble with Zeitronix ZT-2

Kirby · Post by **Kirby** » Fri Jul 14, 2006 7:42 am

I have the settings.ini files set up correctly and the switch point at 2.5. I setup my target afr's based on the voltages. When I lay off the throttle the AFR on the display goes to 21:1, but in MT the WB guage in MT goes to like 85:1. IS there something wrong with my settings or have any of you had similar issues?

Kirby,

Does MegaTune display reasonable values in the usefual part of the range, like 10:1 to 18:1? Or is it wrong all the time?

In the datalogs mine tops out at 21:1 AFR lean on fuel cut, sounds like a setup prooblem somewhere?.

What does it say in the datalog at overrun fuel cut?

Well my datalogs only show voltages not AFR... Here is a datalog of my setup. I have been trying to get tweak to read it and following the trouble stikys, but so far no dice.. I know it's going really righ under boost. Sometimes 9:1. I've been trying to get tweak to give me some help. I'm also posting my latest MSQ so if you have any suggestions I would love to hear them...lol

Mine does the samething. Also when the 02 is heating up and not displaying any value the value shown in megatune slowly creaps from around 12:1 up to 30:1 and keeps climbing.

It does show the correct values after it's warmed up. I'm running MS1 v2.2 MSnS

Mine doesn't fix itself after warm up though. The guage in mT will read that way all the time. If I'm in the throttle and then let off in neutral it will go up to 68:1 or higher.

Added my MSLVV modified for ZT2, the program supplied with mslvv doesn`t work because the ZT-2 has a non-linear output..

Not to be dumb but what do I do with this file? I finally got my log to open in MLV, but MSLVV still gets range check errors or will not open them at all. I still can't get mstweek to do anything with it either...lol
