Lost communicaiton problem.
I always loose the communication between TS 2.0.5 and my ms3 with rc1. I was on beta 18 and beta 20 before and I was having the same problem. I also tried with TS 2.0.0. Nothing changed.
I tried with the usb port of the ms3 and also with the serial to usb cable that diyautotune sells. Same problem.
At idle it seems ok but when I hit the gaz pedal, I almost always loose the communication. But sometimes I can make a pull before loosing comm but it's rare.
I tought it was noise so I added 220uf to the 12v input f the MS but nothing changed. I already have a capacitor on the ignition (near the 6 pen coils). I also added 104 caps on the 5v of the 40 pins socket.
I'm using 6x 2uz pen coils and 6 low impedance injectors with resistor box.
In datalogs, battery voltage is stable (I also have a capacitor on the bootloader jumper).
All my grounds are good, directly on the intake and the sensors ground is only connected to the MS.

I also tried to to drop the comm speed to 57k but it changed nothing.

Re: Lost communicaiton problem.
no, i noticed that the afr at idle is not always the same and I have correction disabled. But the car runs fine and its hard to reconnect. Normally i stop the car and try to reconnect and it work.

Re: Lost communicaiton problem.
and I also used this ms3 on my car and I had no problems while driving more than 1000km in one weekend with a lot of datalogs. But on his car, i loosing communication with TS. Maybe I can add 1 capacitor to each coil and see if it help for the noise...
Is there any heavy duty capacitors recommended to use with 2uz pen coils?

Re: Lost communicaiton problem.
do you think installing this capacitor to each coil will help: http://www.digikey.ca/product-detail/en ... ND/2815201 ?
0.63uF/100v 125celcius
Or i'm loosing my time?
Thanks
