Been messing around with the EMS and FJO wideband. Got the idle and vacuum side of all the fuel maps pretty well dialed in. Drives much better than before even with the timing maps and fuel maps still needing to be tweaked (just a matter of time).

Heres a snapshot of one of the first boost runs.



You can see I still have some fuel to add (varies from 12 to 14 a/f ratio under boost here). A couple more days with the wideband and I'll be set.

The engine load is the 3bar sensor reading of boost level (it varies from 9 to 12 while the crappy autometer gauge is dead nuts at 10psi). I tend to trust the 3bar sensor a little more than the guage.

The thing to notice is I'm at 40% duty cycle on the injectors at 10 psi which means I've still got plenty of fuel left even at ~10 psi.

Keep in mind this is one of the first boost runs and is not where intend to leave it (need to get fuel at 12.5 for all of the boost levels).

Things to note with the EMS:

This unit is not impossible to tune. On the other hand it is not for everyone. The base maps that are out there worked fine on my car. Got it running the first day with very little work. However the maps for the f22b1 are limited and there arent ANY with a 3 bar MAP and 500 cc injectors.

Automapping has the car running like stock in the normal driving ranges (vacuum and low rpms). I've used it the boost ranges but the loads and rpm vary quickly and is hard to stay in the respective ranges long enough for the unit to correct itself, but this is only my 1st attempt at boosting.

The car is running now with none of the headaches I've heard from other EMS users (idling high or dieing at stops, etc.).

I wouldnt recommend trying this standalone without a wideband though (I dont even see how this would be possible).

Cliff notes:

Got boost again.
Need to work on fuel and timing maps.
EMS is very doable.
Automapping does the work for you.

nice post. Hard to see that light aqua text though!

 

why did you go smaller then stock on the bore

 

nice update!

stock bore is 85mm for the f22b1

 

are you sure i was thinking its 86mm on f22's

yup 85mm as it states on the helm's

i wish it was 86

Its throttle. Dont know why it turned out like that.

You can see it goes to 100% and stays there for the run. Not really important anyway. (I dont use throttle position for any fueling/timing).

 

Just curious why not up the boost from 10psi with a nicely built bottom end?

Just trying to understand, researching boost right now since I got a spare engine

 

I'm guessing its cos he is just tuning it at the moment

Dont wanna go nuts on an untuned setup and blow it

Looking good niedejb, cant wait to see what numbers this creation makes!

This is definately why. I have to recreate all my fuel and timing maps and this was my first boosting session to speak of.

This is actually one of the later runs to let the automapping have a shot at getting me close.

Pretty close for the 3rd or 4th pull. Not as good as I'd like though.

 

Hotness. I figured it was tuned awhile ago on 10psi from the sig.

Anywho, good numbers forgot to mention that earlier

 

The numbers in the sig are from a stock f22b1 with a FMU, VAFC and 500cc injectors @13psi w/115000 miles on the engine.

You can add a zero to those with the setup I have now....j/k
