MS-1, V 2.2 brd, MT 2.25, MSnS-E 029q2
Board mods for EDIS 4 (led 17), Fan control (x2), and 2nd Map sensor (x7).
Still testing on stim, to be installed for spark control as soon as I figure these glitches out, fuel soon after. The board has been cleaned thoroughly several times with spray flux remover and a toothbrush.
- LED 17 – Doesn’t flash. Is it supposed to? It does turn off when rpm exceeds about 22,000 rpm! Aside from putting it in the car, is there a way to test if the spark output is working?
- I have fuel cut set at 6500 rpm, and it works. But in the above test, D2 and D3 (inj. 1 & 2) come back on at about 25,000 rpm. ? Not a problem, but odd.
- 2nd map sensor does not seem to work in "realtime" display. I have verified that it does work. 5V to pin 3 and output of about 1.8 V at 97kpa down to 0.4xx V at 25-30 kpa.
- O2 voltage is inconsistent. Sometimes it will not go below ~0.488 volts and creeps up as High as .8 volts with nothing being touched. I leave it for 15 min and when I come back it shows 0.00V and turning the pot it goes to ~1.2 V and back to 0 no problem..? A/F displayed 4.8 to 28.0 when working properly.
I don’t get any error messages and other than the above everything seems to work fine. I think some of the above is probably a wrong setting or some thing. I’ll attach a datalog and my msq.
Thanks for any pointers,
Daryl
