Yup only ever heard good things about the mtx

Ok

 

Quick update, changed the sensor today and so far so good. It's back to 15.1 on cruise and holding fine... Hoping that's solved the problem now

Martin

 

Great news Martin,hope it behaves itself now

 

Thanks mate, me too

Have a problem now with the defi fuel pressure reading

Martin

 

Should flick about 14.6-14.8:1 though, maybe needs another calibration. My car runs steady at those AFR's on cruise. Still your displaying on the safe side showing .4 lean (so if your car is tuned at 11:1 it will display 11.4:1)

 

Thanks mate I'll leave it a week then do another calibration see if t changes any...

Martin

 

Not sure your getting a true AFR of 15.4 at cruise, your lamdba should be correcting it to close to stoich (14.7) unless your running open loop i guess ??

12.3 on full chat is quite lean as well but if standard ECU probably right

My MTX at cruise fluctuates rapidly from 14.3 to 14.7 until over 3000 ( out of lamdba )

 

I'm not sure now as even after the new sensor change i got the same problem, maybe it's wired incorrectly? Company have now offered to replace the controller to see if that works...

Took it out again yday to re calibrate and seems to be working fine again.. Has to be a problem somewhere else

Could be how it's wired up? How have you done yours?
It's possible you are getting interference as this is how it's describes in the instructions....
Circuits that share power with the vehicle’s stereo, ignition system, ECU, lighting, or fuel pump should not be used. When in doubt, create an additional circuit using an automotive relay available at any automotive parts supplier.

 

I didt wire it mate so not entirely sure..
I think it was wired to ignition though, could this be why the readings are so off?

How has everyone else wired there's? Maybe I need to rip it all out and start again with a relay

Mine's on a classic,I was going to run a separate circuit direct from the battery with an inline 5A fuse and relay but when I took the trim off from under the steering column I found an old parrot hands free kit which had its own circuit,the hands free kit was no good as someone had ragged out the control and mic so ended up using this to power my lc2 controller,I've had it in for a few weeks now and it runs fine.

 

Just poked a live and earth spade into the *** lighter wiring, not a problem at all, the power source isn't that fussy, the internal wiring from sensor to gauge has to be excellent though, but usually your not messing with this

 

Not a innovate but my instructions show this

 

Maybe the innovates are fussy compared with others. My AEM works mint

 

They seem to be those instructions are for my ntk afr
