something something.... DANGER ZONE!

Especially where this one has a properly tuned intake manifold. The capri b6d is tuned just like a Festiva (TQ curve) but this engine is a different animal. I've got a BP ecm I'm not using right now, if you want to try. I'll mail it to you Joe.

someone needs to go on a dyno and compare

b3 ecu/injectors/vaf
b8 ecu/injectors/vaf
bp ecu/injectors/vaf

my money is on the BP stuff

back in the day a guy named bondo swapped a b6 using bp electronics and he said it worked perfectly pulled hard to redline! take advantage over that dohc head.

[shorestiva]

Feels like it to me but my butt dyno isn't calibrated the greatest.

[Advancedynamix]

Is this engine pulling hard all the way to redline?

[shorestiva]

I don't lol. I have a bp01 which I believe is a b8 ecu.

[Advancedynamix]

That's a possibility. It doesn't hurt to try, if you have one.

[shorestiva]

I stopped and checked thus morning. Pretty sure I sold it. Would a bp ecu be better? The fuel curve might match this engine better since they both have vics?

[Advancedynamix]

I might be able to get a b6 ecu. I'll check.

[shorestiva]

57 psi stock vaf adjustment. mid range is good. leans out to 15-15.1 at redline (6500 ish). pulls really hard feels great.

[shorestiva]

Any idea on what my pressure limit should be? I'll try digging around to see if I can find a set of ev4 or ev14 injectors that are close to the right size.

I think I sold my only sohc 1.6 ecu. Might still have it stashed somewhere though. All the stock stuff I have laying around is for a b3, b6d, b6t, or z series. I do have a 16v 1.6 sohc long block here but it didn't come with all manifolds or electronics.

[festyfreak39]

Also sorry but why haven't you tried the B61k and green top injectors/vaf yet?

[festyfreak39]

Do any of you guys have a spare b6D exhaust manifold?

[Advancedynamix]

Bumped it to 52ish and backed off a click. Better but still leaning out up top. I'm sure my neighbors are loving the full throttle testing at 630 am lol.

You should be able to run 60psi to those injectors without reliability issues. Dragonhealer has run even more on stock Miata injectors without failures and they are nearly identical to Festiva injectors, besides flow rate.
Ryal also reminded me that spray pattern efficiency is reduced with more pressure on the EV1 injectors, so you may want to get some EV4 injectors down the road for better fuel mileage. I think you can get this system dialed in to work reliably with this engine.
