Well as the title says...im running lean...at WOT im anywhere from mid 13 to 14 to 1. Kinda freaking me out a bit. I have not been able to datalog yet. I have not heard any knock and I really dont want to I'll go fetch a serial cable and try to get some logs. Maybe that will help out

just thought of this question....what would cause the car to just start steadily go lean...when i got the car back i was in the mid 11s and now mid 13 to 14s.???? Nothing has been changed or touched for that matter since its return.

 

Fuel pump losing pressure?

 

colder ambient temp.

 

was thinking it could be fuel pressure but I dont have a fuel pressur gauge to see...

I definitely know its not colder temps...getting hotter everyday it seems like lol

I wasn't able to datalog as my laptop does not have a serial port...sighs...maybe I can get one from work 2moro

 

dont boost while that lean. take it back to ur tuner and get it on a dyno.

 

the ECU may have switched to a different part of the fuel map, trying to instinctively lean out the A/F ratio...stupid ECU's too smart for their own good...

good luck

Has there been past issues with the ECU trying to take back over with the Utec? I've heard of the EU having that happen. Sharif is now a good distance from me and it will be a lil while before I can make some arangments there...I'm hoping I can find something local just to use their dyno

 

Just stating the obvious, but make sure if you have the remote map selector, that you haven't changed to the stock map or something by brushing against it. It has happened to others.

 

I don't believe I have the remote map selector. Atleast I have not saw any type of switch anywhere.

 

The only setup that won't be subject to the tune "walking" is a true standalone...any other piggyback holds the risk of the tune varying to some degree..usually not enough to make it extremely unsafe, but from what you reported, you are definately running way too lean (and unsafe)...

I went through this a few times with the emanage and EU, I had to periodically adjust the tune to richen up the tune..eventually, it stayed put and stopped compensating in the wrong direction

 

I can get an adaptor for the serial cable. Think I should still try and datalog?

 

what a/f gauge are you using to read the ratio? alot of the gauges are really not accurate from what ive seen

 

im using the innovate standalone wideband...this may be a dumb question but to datalog...should i just go from a 2nd gear roll wot just in that gear?
