FD Won\'t Start After Single Turbo Conversion

[BlitzBoy]

I finished work will check the thread later on,
personally I would disconnect the FJO temporarily and revert back to stock wiring just to get it running.
I think you only connect the FJO to secondaries with no resistors

Just had a look at the rev/idle settings as well and they are all at 0rpm!!!

Should I just set it to self learn again?

[gonzoninja]

Update on this: Looking at all the settings it looks as if they have been lost!!!

So I think it is trying to go into self-learn mode again. Talking to a local garage they reckon that it\'s not unheard of (although rare) for the Power FC to lose its data, or rather the Map just doesn\'t load up or something.

[JayDee]

is it a second hand ecu sounds like it could have a password on it or be protected

[gonzoninja]

No. I bought it brand new a couple of years ago. It\'s had a couple of maps put on it.

Apparently it is rare that an Apexi loses its map (or rather it just can\'t find it) but it does happen.

[BlitzBoy]

who put the maps on it?

[shaunwil]

So Its definately Lost the map ??

The FJO should find what type of injectors your running (low/high impedance) and adjust to suit. Theres no way it would wipe a map. Its just a signal convertor.

if someone has loaded up a map on Mr Gonzoninja Apexi they protect the map and it will only show zeros on some of the settings through the commander

[Jürg Hensdiek]

The later models of the FC have been known to totally drop data. Possibly due to poor quality control during the \'hard\' years Apexi went through.

The most recent map on it was a running in map put on by Carl Hayward. I don\'t know if he protects his maps?

[BlitzBoy]

He may have done some tuners do, give him a bell, things like the Timing map etc will defo show 0s when protected on the commander

[gonzoninja]

Spoke to Carl Hayward and he does password protect his maps. But he is puzzled why this is happening if the primary injectors have stayed the same.

Think I might try and isolate the FJO injector driver, to see if that\'s the issue.

Okay, well this weekend I fitted a wideband lambda O2 kit, and by messing with the fuel pressures a bit I managed to get it started and running.

Unfortunately it seems to be only running on one rotor...which isn\'t good.

Looking at the AFRs, it seems to start at about 13.3, which is a little rich (I guess) and seems quite steady, but after a while, it seems to hunt a bit again and the AFRs go all over the place, ranging from about 12 point something, when it revs high, dropping down to 16.8 when it gets down to 1000 revs (is this too low?!).

Haven\'t checked the spark-plugs yet, but if it\'s been running rich would this had fouled the plugs badly enough to stop them firing?

[shaunwil]

Did you isolate the FJO ??

The plugs could have fouled up.

No. I just messed around with the fuel pressure a bit. Got it running on both rotors now. It is lumpy as hell, but the main thing is that its running. AFRs are about 13.3 when the revs rise, so it may still be running a bit too rich.
