ZXBob,
Did you ever run your turbo bike with stock timing, and if so what do you think?
Harry said on stage 1 OEM timinng is ok to about 8 PSI, if I recall.

Hope you don't mind if I interject?
Bob likely won't be around till evening.
I spent quite a bit of time on the phone with him in the past, bugging him about his setup
I'd be very careful, I have seen 2 stock compression zx14 with 9 psi stock timing,burn motors
Bobs, pulled timing with EFIR at 5 psi and ~ 6000 rpm if I remember correctly.
I know muzzy suggests limiting 5 psi to their stage 1 and for good reason.
Blown engines are bad advertising.
Do you really need that much more power on the street?
I would think its pretty lazy off boost with -6 degree static.
Schnitz doesn't make the efir any longer.
Consider the MSD SB6?
You can program multiple timing curves based on any 5 v analog signal, ie : boost included! Built in programable shift kill and delay funcoins, shift light, which also could be used as a trigger for auto shift!
The SB6 can also be programmed for 3D timing curves based on Boost and RPM, and can be made progressive timing maps/programs, not 1 stage of timing pulled at 1 trigger point like the old efir.
If your going after more power its gonna come at a cost, be safe rather than sorry!

I did ..... but only with good fuel (not pump gas)
I lost 17 HP with the EFIR on pump gas ... "but the bike still lives"
The new owner just ran the bike in a mile run. It performed beautifully !
Sometimes the air has so much to do with when and how much boost it will
make that its better on a stock motor to pull timing out.

Have 20K on the Muzzy stage 1 @ 5 lbs boost no timing pulled. The Ape manual has put more power into the low end and top end. Installed the turbo at 10K with rattle. Bike is very responsive new crisp throttle response. Scary.

Thanks all. Dubious, I initially wanted to go with the Schnitz box, to discover it was discontinued. It seemd a pretty simple install and setup.
I didn't then consider the MSD cause of needing the know how about the 5 V signal and not knowing enough about the 'do's and don't' for this bike with a blower. I feel a little more comfortable now. I'll check into the MSD unit again. I'd like to get that timing back to OEM until there is some boost going.
Too bad there is not a gadget to tell just before 'engine knock' and set the timing back accordingly.
Along with that idea (anti-engine knock) I was wondering about changing the AF to 13.1.
dreams.
Thansk for the cautionary. I am not willing to jeapordize my bike. $ is tight now that we retired and the kids spend it all.
--- just checked the $550 + price on the MSG unit... that'll have to wait.

Here is the new cheaper alternative, which I would have gone with except I want the air shift kill ability of the MSD SB6.
Dyna Arc-2... multistrike!
Read more here:

Also, schnitz had the SB6 on sale last month for ~$440..... maybe try them and see if they can still do that?
0-5v analog really is quite simple, all the sensors work of a 0-5v signal is all.
Both units come wioth harness and are plug n play anyway.
The software would be the only thing to get your head around, and from what I have heard both vendors have great tech support !
