How to scale the HPFP pressure sensor

[Fagwagon]

what kind of answer is that...tease.

[RayRayBauder]

fuck fuel

[Applied Tuning]

We will have some results of what the MAzdaEdit software can do in about 3 days. 08 MS3 with an intake and turbo-back.

Did have some decent luck with it on a 07 2.5 n/a car today. Even though it wasn't developed for that ecu. Good results nonetheless. Still needs some work. But I have more positive aspirations about the MS3's.

Not sure what you mean by this. Is your software able to address fuel delivery as discussed in this thread?

[djuosnteisn]

Yeah man. I've had enough secrets and hype for this car. I can't stand it anymore. If this can control the fuel injectors, let us know. Can it control timing? Or rail pressure? Both?

How well are the tables defined?

I really do hope that you posted here in this thread because you have a way of controlling the fuel rail pressure if not then stfu.

[KoukiS14]

I've been looking around, and there are a number of 3000 psi sensors that may be candidates for replacing the stock sensor. I think because of the electrical headroom issue with the stock sensor, a 3000 psi sensor with an electrical scaling circuit may be a best final solution.

Of course, if the pump can't make 2200+ psi, or the injectors don't function properly at excessive pressures, it may be a moot point.

[djuosnteisn]

I've heard that the pump can make up to 6000psi, and blow up the fuel rail, lol, so pressures should not be an issue, but injector function is a definite concern.

I'm sure it would be fairly easy to make an adapter plug to run a different sensor. And if the new sensor was on a 3000psi scale, it may not even need a scaling circuit, just some tuning.

I think baby steps are important though, hahaha. I built 2 circuits last night, need to get a few more parts tonight and build 3 more.

I think the likely candidates are:
Socks
JJ
Superskater
Mark (if he wants one, not sure if he does since his stand back already does it)
... and who else do you guys think?

[tmtbiker]

Socks
JJ
Superskater
Mark
Yoichi..although he may be close to maxing out the 2871
SS..isnt he close to running? is he using the sb?
and wtf is randy up to these days? there used to be so much DCR hype..just another mirage i guess.

thats about all i can think of.

[djuosnteisn]

Yoichi is SB AFAIK, so is SS. They're welcome to them if they want it.

Speedsixx guy is going BT and getting built right? don't think he's running yet though.

Lex, you want one to play with? I know your not super BT power hungry mofo, but you'd probably like to play with one, right?

[phantom3]

samsel450r might be a good candidate as well.

Anyway, I got the maps confused and ended up putting the meth values in the fuel pressure map. The car acted weird and when I had discovered what I'd done I knew that we could manipulate fuel pressure. In later discussions with our machine shop owner - builds Winston Cup engines so I listen to him - he indicated that one of the reasons he felt we were having problems making 5-600 hp was fueling. He wanted us to change the injector pulse timing. We can't do that yet - Lou's new standalone will be able to - but we can alter fuel pressure. I'll be the first to admit that I have never believed the fueling arguments that Haltech, Lex, and others have made. Our cars were pig rich at the tailpipe and made power when we leaned them out. But, have dyno, will test.... I tuned Orlando's car using fuel pressure as one of the variables and his car REALLY responded. I don't have that dyno but I'm sure he'll post it soon. Finally, Haltech, you were right. Man, that hurt...

I guess hell finally does freeze over, eh?

[djuosnteisn]

Hey hal, you want one?

[Haltech]

You should give them to the big power guys first bro. But i commend you on pulling this off... its going to be the start of something good DJ.

[socks]

Kevin,

i was curious if you saw that.

DJuosnteisn,

let me know when your ready to send it out, ill cover parts and shipping at the least.

[djuosnteisn]

Part's are pretty cheap man, i almost consider this beta batch a gift to our platform in hopes that indeed something good comes from it.

I'll take you up on the shipping though . Probably ship in a day or two.

I havent had much time to hit the forums and read much with 16 hr days at work and family. My jaw pretty much dropped when i saw that post.

[Lex]

Dustin, won't need this now as my car has a stock turbo and is going away for the winter as we discussed.

If the beta tests go well, I have some good ideas on refining the product.

[Fobio]

looking forward to results!

[wassup61]

I can volunteer my car.....when i get some time.. I have standback and all the flashes, big MAF, 3076, built motor, port injected meth

[socks]

you dont need it if you have the standback...

to tell ya the truth yes I have a gt3071 with most supporting mods but I planned on doing the install on stock bottom end.

If my set up is anything like 18PSIWhiteMs3 i will make more then 400 whp and that scurred the crap outta me.

seeing how I have 50k on the dot as of tonight and 18psi has 8k? lol

when I do the install I plan on driving to Akuma ASAP to get dyno tuned.
I trust stock bottom end with 400whp is safe enough with a good tune but lets say I install this new sensor and have Akuma tune for it?..

I don't wanna be the first guy to find out how much power a 2.3mzr can make before I go boom on stock block!...lol

I suggest 18PSIwhitems3 and or samsel....they both have gt3076's on stock motors and maybe one will be willing to see how much more power they can make with the new sensor and tune.

If you can get this sensor out to one of them and we see well over 400whp on stock bottom blocks then I'll deff be down for the senor.

as of now I'll do my install (hope to make 400whp) and when I feel the time is right i'll build my motor. I hope installing the 3071 with 50k I won't blow a hole in the block if anything goes wrong..lets just hope for a fried piston ring and low compression then I will have the will to build..if hole in block...I'll have to think real hard on what I wanna do.

again...contact 18psi and samsel and lets hope they are down for makin 500 whp on stock bottom. if they can I will....

ty for thinking of me as "that speedsixxx guy" lol =)

[djuosnteisn]

Okay, cool! GL, your brave to run that setup on 50k, might wanna start saving a bit month to month for a build just in case. Look forward to your tune.

[SpeedSixxx]

are you Canadian Dj?

im not trying shit. my car runs fine, i dont want anymore power on my stock motor. i spent 1000 on tuning in the last month between the SST and this gt3076. Im done spending money on tuning lol.

i think you have a man crush on my speedsixxx. your always talking about me and shit. leave me out of this. why don't u try to pop your motor.

[djuosnteisn]

I am not canadian.

I'm a cowboy.

[phantom3]

We have cowboys in Canada. I just finished working the Canadian Finals Rodeo...














Bullfighters are pussies.

[SpeedSixxx]

18psi will pop in t-minus 400 hours!

[bf360]

so now that weve established 18psi is a pussy, who has the balls to try this?

[SpeedSixxx]

Originally Posted by bf360 so now that weve established 18psi is a pussy, who has the balls to try this?

ill take one DJ if ya wanna send me a built unit..

when i get tuned i'll leave it off and see what i make..

then i;'ll add it and re tune same day and see what i can get out of it..

fuck if i blow i blow. then i'll build..

up to you DJ wanna send me a unit?...

my goal is to make more whp then 18psi so when i roll race him i rape him...im not pussy!

[bf360]

lol your guna need about 420whp to beat him from a roll

but he wont race yet anyway his car is a garage queen lol

garage queen till the spring : O )

[SpeedSixxx]

ill be waiting till then.....hope ur 8k motor holds compression when u restart it after months of sitting...

[djuosnteisn]

Sure i'll send one. I've got to finish em up and test it out. Hopefully have em done manana, and ship on friday. PM me your addy speedsixxx.

[djuosnteisn]

Double post merge will probably kill my bump, but oh well



All ckts are built. I need to test them one more time in their housings, and will probably ship them tomorrow (sat) or next monday. I'm leaning towards monday, cause that will give me a chance to at least list the tables that will likely require tuning.

I also want to stress that this is completely experimental on all our part. Install at your own will, and nobody's responsible for any damage incurred if there is any. If you guys want to wait till my pump shows up, and let me do all the guinea work, i will, and i'll post up any issues as they pop up.

Right now i'm just sending out 4 units, to Socks, Super, JJ, and speedsixxx.

Only concern i can think of right now, is that the circuit's output (since it's a single supply op-amp) clips at a lil above 4V and just below 1V (on the output, ecu side). But from what i understand, the ecu would never be commanding for >4V or <1V, since idle is 1.4V or so, and 1600psi is 3.8V. Again, i'll guinea this shit if you guys want to wait.

[Deadman]

great news dude.... things are beginning to get interesting!

[superskaterxes]

shits cracka lackin'!!!!!!!!!!!

on another note, dustin did make these for free and isent charging for shipping or parts cause hes that chill a dude but i threw him 10 bux anyway to cover it all. dont be a jewbert and send the boy some $$$

[djuosnteisn]

Send me lots of moneyz, then put these mini bombs on your carz. Each scalar circuit comes with moth ballz for the gas tankz!


I'm down for pitch-ins on the shipping, but wouldn't ever charge for a "beta" circuit. This is purely R+D in my mind.

yea but RR charges people for things before they are even available so they can continue to do R&D how come you dont do that?

ROFL

[phantom3]

DJ,

Do you have a schematic of these available? I wouldn't mind making one up and testing it.
