E8 weird problems

Postby jeff b » Sun Jan 24, 2021 1:50 pm

Hi all, I have wired up quite a few E8 ecus on Honda engines.
I'm having trouble with the latest one, lots of weird things happening.
When I power up and open gauge page battery voltage reads 16v? The coolant temperature is jumping all over the place, and TPS doesnwork at all.
Tried updating firmware 32 (35 doesn't seem to work as well) still same trouble.
I swapped out for another e8 ecu, loaded with same firmware and same tune and it works perfectly.
This rules out any wiring, setup issues.
Is it possible the e u is damaged internally?
Thanks for any insight
