What's up guys, long time no post, but those Honda guys are getting me anywhere and I'll see how the old fam could help out

Here's my set up 97 Acura GSR obd2

Here's my problem

Greddy GSR turbo kit
18g
type 31 intercooler
type s bov
8:1 FMU
310 injectors
Missing Link
Inline

BTW, i'm only running it at 7 psi
past fuel set-ups include/d

Greddy blue box
Filetofit's AFC hack circuit

Symptoms:

When I had the blue box, it ran great for one day, than the next time I drove it (I dropped it off at the body shop for 2 days) it ran like crap, I mean anything over 1/4 of throttle sounded like it was dumping too much fuel into the injectors, kinda like a flub flub flub rapidly. Ok so I thought maybe the blue box is fucked, got rid of that..............................

Bought a Map Circuit from File to Fit, forget about it, wired and soldered everything correctly, could not get the car to idle at all with the damn thing with 450's and resistor box, got it to idle with the 310's but could not tune it down enough to run with it, fug that, took off the circuit and 450's and put back on my 310's and bought a FMU/missing link/pump set-up

With the FMU route, it ran just the same as the blue box but a little better with the 12:1, meaning I could go only about 1/2 throttle before it had the sputtering

when I put the 8:1, I can go about 3/4 throttle in first before it starts to sputter but it still feels PISS SLOW, WTF? I've never had this much problems with a turbo set-up before, I have no clue what the hell it oculd be

It feels like something is holding the car back and not letting it go when I give it full throttle..........anyhow, any input would be appreciated

I just bought the SMC, so let's see how this works

Yes, I did use a degree colder plug,
We did replace the distributor
We had an open downpipe to make sure it spooled better
my rear o2 sensors was broken off but we replaced it when we put the 8:1 in and it still doesn't work (we used a o2 sensor off a 92 prelude), we pulled the codes and it doesn't pull anythign up for the o2 sensors so we're assuming it's working


Anyhow, please I'm at my wits end, i'm seriously thinking about selling the damn thing.....

Hmm.......forgot to throw this in I've got perfect 210 compression all the way across

BUT

WHen we had the 450's and the map circuit by Filetofit

It ran rich, I mean REAAAAAALLY rich

so rich my spark plugs came out jet black WET

but it was already running like crap before that too, it kinda happened right after I changed the plugs from stock to the one degree colder

I know it's the right plugs bkr7e-11 #1283

But ever since the plugs were "fouled" and soaked with fuel I haven't changed them, just wiped them down and off so I figured they were ok, I only had it on the car for about a 10 minutes drive home running rich as hell.........

Oh well, i'll change it tomorrow and see what happens

Well what I would do first is adjust your idle fuel pressure down. Correct me if I am wrong, but the 310cc injectors are larger than stock on that car correct...? If so, the 8:1 disk is probably still dumping in too much fuel. I would try a 5:1 disk and keep a good eye on your gauges. Do those cars use a MAS? If so I would monitor the voltage coming out of that sensor to be sure it is within spec. If you use a MAP sensor the same way our cars do, then I would monitor the voltage coming from that as well.

B.T.W. did you try replacing your spark plug wires? This could also cause that.

I think your boosted fuel pressure is too low. If its fine at idle and cruise, but sputters at anything over 1/2 throttle or so, you're either getting too little fuel under boost, or your wasteaget isn't opening to help control it.

Can you give us some more detail? Idle pressure, max boosted fuel pressure?

Idle pressure is about 35 psi

Max boost is 7 psi on the 18g

you think a messed up Map could be the problem?

I'm going to change the plugs out tomorrow, they had to order them in today so we'll see what happens,

Much thanks to all, I knew Dino would have something helpful to say, he always did with my RS-turbo, damn automatic turbo RS ran better than my freaking 5 sp turbo gsr, Oh well, time to sell this one and get another Deezmen
