Stock 1.8, Fm2 kit, 2560r, ID725's, FM big spark kit. Pretty happy with numbers on a Mustang dyno. Now if I can just make it to the track to validate..

EDIT: The car also has a yonaka catback, It's a 2.5 inch.

 

Looks good
I'll check your logs and tune today

 

Are you running EBC?

Looks good man!

I've seen your posts in the MassMiata group!

 

would have been awesome to see what the car made before he turned it down

 

He turned down boost for that run?

 

Not boost, but timing and fuel. Well, kind of. I e-tuned this car, and recently he had a shop throw it on the dyon, the tuner/shop basically lowered timing by like .5-1 and richened up fuel by like .3 so probably a few hp, nothing drastic. He's just a few keystrokes away from 250hp. Overall really solid plot and OP loves it

 

Yea running a diyautotune EBC. I think I'm just a dyno jet run away from 250hp+. There's a dyno jet that's local to me, seems to read on the high side. I'll throw it on there when it gets colder out to get a few extra "internet ***** points" as I like to call them haha. Only thing that matters now is to take it down a strip. I should expect 108-110mph if I'm assuming correct?

 

106-107 would be my guess. My msm trapped 106 and put down 230 dynojet/ 210 mustang.

 

I didn't see a build thread for this car. What exhaust manifold are you using?

Intercooler and intake setup?

Thaaanks.

Everything except the injectors and boost controller is from the flyin Miata fm2 kit. Injectors I got "used" only 1k miles on them and then they were cleaned and flow tested. I would make the worst build log if I wanted to make one. I never take any pics when working on the car, plus it's a pretty much cookie cutter build.

 

Yeah... woops. Must have looked at that post 4 times and missed that line of mods every time... #foreverblond


Thanks for the detail, sorry for making you write them. Good numbers, especially at the very top. Usually I see power nosediving well before 7k. Yours holds nice and steady. I'm guessing that has something to do with the ebc tuning? Unless you have a flat top im.

 

Its an all stock 94 motor so no flat top, and it's 15psi steady so it's not some trickery of adding boost taper to hold power. Dunno why it holds so nicely.

 

It's because a 2560 is fine at holding this amount of boost. I don't know the point where it starts to drop off but I would guess a couple more psi.

 

Could be the timing up top too, no? 94 has the lowest compression 1.8 pistons @8.8:1. Would make for a more aggressive map than say... an nb1 or nb2.

I'm guessing Miner tuned it, huh? His dyno is referred to as the heartbreaker dyno for a reason. That's a very respectable all around. Solid!

 

From my experience tuning my own car, timing did nothing to help spool or keep boost pressure. Exhaust gas flow is what matters.

 

Would you post your VE table? I'm interested how VE changes up top as torque drops off.

 

my 2560 held steady until about 18.5 psi. Above that, it would taper down to 18.5 as rpm climbed. By then it was probably spitting fire anyway.

 

Yea, Miner tuned it, when i asked him about possible power output he said "low 200's" so I was surprised when he said it made 240. For the hell of it I'm interested in taking it to Baystate Dyno, see what their dynojet spits out, they seem to read really high. And maybe I'm wrong, I thought 94-?? had 9.0 compression ratio.

Here's my spark, VE, and AFR table. The spark map is bassically the one that came with the DIY basemap, just rounded to nearest .5 increments as stated earlier. Also, how would the VE show torque loss? its flowing the same amount of boost, and building more horsepower the higher the RPM, so it never really loses any VE. Unless my understanding of tuning is completely wrong?




I didn't think this thread was going to be so popular.. Maybe I should make a half assed build thread.
