years ago i built a 2a0 and its worked mint.

i decided to build another for my other car to lean it out (rescaled the simulated narrowband out) so i purchased a 2y2.

then i looked and saw that the documentation wasnt the best. oh well.

i put the final touches on it today. cut the hole in the case (dremel and razor blade) for the screen and trimmed some length off of the display pins and soldered them to the included pins. i soldered the sockets to the board.

i didnt use the ribbon cable that was supplied. once i was sure it fit, i attached the sticker and then squished the display into the back of the sticker and smoothed it out.

everything fits like a glove. the display stays attached to the lid when you take it off and just unplugs from the sockets on the board. ill have to take some pics.

one question....

i read in the 2Y2 documentation that there are optional buttons that i assume are for display control.

does anyone know if there is coding in the firmware to use these buttons?

thanks

Brian

It is almost a year since my last e-mail contact with Peter regarding the 2Y2 firmware (there are some bugs). Then he promised to have a look at it soon...

We are there still - no proper support for the on-board display, bugs are not fixed, the WButil is not updated to properly support the 2Y2.

Sad

I've sent him several pings, at first he was sorta responsive, last couple of months he never replied at all...

Hi.
I didn't get any response from Peter for a while as well. Is there still anybody at TE?

One serious bug: no data from the thermistor is being sent, and the other bug is related to the soft heat-up: there is the sharp inrush of the heater current.

I'll try calling them, but because of the time zone difference - it's difficult to arrange, we are antipodes. Smile

Hmmmm I forgot that I posted my success/question here.

I began using this unit this spring on my turbo 88 Plymouth reliant. Is the 100 duty cycle heater control damaging to the sensor?

Is it actually commanding heater current or is the led turning on with mcu control (didn't look at the circuit diagram yet...)

Thx

Brian

followup to my original thread. i hooked everything up from my car to the 2y2 like i have done for my 2a0 for years. map sensor, tps sensor, rpm feed from coil low voltage side, narrowband out to my ecu and everything seemed to be fine. took a few runs around the block and everything was fine.

then i took a longer ride and on my way home, the afr just jumped up like the values were being doubled all of a sudden.....

i then connected the unit to another sensor and it appeared to operate normally when i tested it with a lighter. so i free air calibrated it to that sensor and tested again with a lighter. appeared to be fine.

so i pulled the original sensor from the exhaust and zip tied it to the cars antenna and did a calibration and got the sensor reinstalled and hooked it back into the car.

fired it up and it appeared to be fine. went down the road. fine.

came home, hooked it to the laptop and all of a sudden, back to 30+ afr values.

any guesses? it appears to be loosing its calibration.

for now im going to hook my 2a0 up and try that for a while to rule out the sensor.

thanks

Brian

update... did the same thing with the 2a0. all of a sudden 30+afrs....

so i swapped out the sensor for my old sensor and the cable too for my old cable.

has been fine so far even after a 200 mile trip. must have been the sensor and the cable.
