i have a ? will the 500 cc inj. work fine with a32 maf till 290 whp or you'll have idle problems

 

Assuming using a stock ECU, you'd be so rich during cold starts you wouldn't be able to run.

People with that setup and 370cc have to turn down base fuel pressure from 34psi to 26-27psi just to keep cold starts healthy.

I don't think you could compensate for the 500cc unless you had eManage at least. Then again, if you're only expecting 290whp, you only need 370cc injectors.

 

can you control the pulse width with safc maybe,,, and if you turn the pressure down will that be ok for high rpms

 

No, the SAFC can't compensate for cold start enrichment.

The FMU or tuning will provide additional fuel at higher RPM.

 

So, turning down the base fuel pressure, A32 ECU, 550's, z32 MAF, and SAFC II should be good to run 10lbs of boost or less. Sounds good to me.

 

Yes, around 320whp(15% driveline loss) can be supported if turned down to 26psi@idle / 35psi@WOT at a safe 80% duty cycle *IF* this combo proves viable.

 

so what's gonna happen if you go over 320 whp,will lean out

 

No, you'll have a higher IDC

 

DC@90% = ~360whp
DC@100% = ~400whp

Or you can have a FMU or aux fuel pump raise fuel pressure above 35psi to keep duty cycle safe.

Plenty of room with 555cc to safely work several different ways.

 

I'm just jealous you took the time to come up with those

 

It's a simple calculation, so no time really.

Just wanted to keep bumping this *UNTIL* someone confirms/denies it can work.

You find $300 yet?

 

I'm about to put something in the F/S section....

 

if someone buy some of my stuff for sale, i may be up for it too.

 

I guess I could test it out, but it would not be for a while

 

good luck with the kit mike!

 

We will have a little install meet in the spring. Neal will come down and you and some other local guys should come over. Gonna use the winter to save and buy some quality fuel management.

 

i'll come too.

 

So, I am now in the position to do something with an A32 ECU, Z32 MAF, larger injectors, FMU and SAFC.

What should I try.

Z32 MAF, 370's, and FMU?
Z32 MAF, 550's, and AFPR

Looking to turn the boost up to 8-9 psi.

 

Well, we just put the 660's in my car (I think the largest size Dave offers) and it's idling and starts up easily. We did have to put the push button starter in, and idle fuel pressure is at 26psi.

Z32 MAF
Stock A32 ECU
SARD FPR

And of course the emanage for tuning.

 

I dont know if you can tell this way but. Im running a A32 maf and the safc says that im using about 75% of it, What kind of horse power do you think im running? im Running about 10psi from a stock ct26. Im guessing about 250whp. But I was wondering if you guy could come up with anything fom the % im using of the A32

 

Thanks...GREAT info, however we were trying to determine if this was possible withOUT the eManage correction factor.

Or are you saying you didn't use the eManage injector size correction factor?

 

I'm not sure on that...Bernard can probably answer that though.

 

I am at around 80% on the AFL reading via the SAFC and have 260whp and 260wtq @ 5psi.

 

the most i saw was 83% at 9 psi s/c

 

This is basically the setup im planning on running.
I want to do the SAFC II, Z32 MAF, A32 ECU, and 550 cc injectors. But it sounds like problems will occur, and the e-manage needs to be used for correct tuning. But, what if you ran the setup with an AFPR at with base pressure at ~24-26psi, and a FMU with a 3:1 or 4:1 disk and tuning MAF % with the SAFC do you think you could get a decent tune? This is assumming 6-9 PSI of boost.

Or would the 370cc injectors be a better bet, using the stock FPR and only using a 4:1 FMU.

Let me know how you experimenting goes...

 

emanage is only a little bit more and it opens up a world of tuning options.

 

What scared me off with emanage is the accesories and software, i didnt do any investigating in what i would need with it? What software and accesories is needed for us?

 

I changed my mind for the moment and will probably not try that set up. Will most likely get a JWT 550 and Z32 turbo tune and call it a day.

 

Why not emanage?

 

probably ease of use. its just plug and play. there arent any more toys that you have to worry about either. Plus, he can use his brother's larger injectors so he can up the boost even more without maxing them out. Didn't mardi use the jwt and then tune with emanage for the 740's?

 

simplicity mostly. For my goals emanage does not offer much advantage.

 

Well well well.....I just started my car with 550's, Z32 MAF, and stock ECU and it started like butter and idled great!

I forgot about this thread and was not meaning to test this, but it works.

**edit** This is with a base fuel pressure of 43psi. I do not have an AFPR

 

beautiful, now get your money back and get a wideband.

 

Time to have JWT flash you a 370cc/Z32 tune w/increased limiter and then pick up a used Blue eManage/harnesses/support tool for <$250 nowadays.

 

Just drove the car around and got into a little bit of boost in 2nd. Car ran smoother than it has since the turbo was installed. Have started it many times with no flooding issues. Tried to get it to flood and it still started fine. these injectors rock. They are within 2% variance of each other. Statically and dynamically balanced.

At the moment I don't want anything to do with JWT. But I am going to call them and see if we can figure out how to fix this problem that they are having with their tunes. I would really like to run their ECU. I am willing to work with them if they will at least acknowledge there is a problem. But if they start with their bull **** I am not gonn mess with them.

I would be happy if I could install this 10psi spring with the Z32 MAF, Deatschwerks 550's, stock ECU, and get it tuned via my SAFC. That would be enough for me.

 

Time to dyno or get a WB02 Mike....
