does anybody heard or know about JET PERFORMANCE ECU?

[driftfreek]

i bought this car off this guy, which came with a JET chip. its seems like they didnt tune it write to the mods i have cuz im not getting all the hp im suppose to get...has anybody heard about this site or have a chip from this site?

[S13FASTBACKSR]

you never get all the horses it says it will give you..they lie to you hoping you will buy it..what are the mods?

[neverlift]

I have already told you. I have seen the code, it is just more fuel and a bit of strange timing imo. JET will tell you they custom tuned your ecu, but did they take your car for a day or 5? NO! A custom tune is custom to your engine and needs, without testing on the actual car the tune will be used on the tune will be very padded to suit you or me or pimp c. I think you have alot of flow without the right fuel curve for how you are setup. If I was to read that chip it would look just like stock+ time and fuel across the board, which is not tuning. The ka likes to be leaned out in spots and have plenty of fuel in others. hey s13fastbacksr were you in jacksonville the other day off normandy? If so sweet ride man.

[S13FASTBACKSR]

for the one above me

and im surprised your engine is even running good without any problems..those chips if you ask me are garbage and a bunch of

by the way no i wasnt in jacksonville and if you are referring to the skyline in my avatar picture as my ride then thanks but thats not mine lol i wish

[neverlift]

sorry I should have looked at the avatar closer, its a skyline what I saw the other day was an s14 with skyline tails. my bad! No those chips are not trash just file 13. Some people have good luck with them. I dont personally know anyone with a chip that was like wow. A programmer from jet or superchips that allows tuning control on chevy,ford,dodge is great but not offered. The consult is close but a nissan thing specificaly. If you find a chip company that will retune for you at no charge until they get it right. I think enthalpy(spell check) does this for a price. I think driftfreek should get an afc and af gauge. It will probably be the easiest way for him. Only like total of ten wires to splice/hook up. Also lets you tune while cars runing.

I use eeproms and love it, I make a tune,go out and test the tune then adjust accordingly. Might be time consuming but I am cheap so paying a dyno shop or other route was out of the equation, plus I like to say I DIY'd it.

[driftfreek]

i have pdm cams, JET ECU, n bolt ons. the guys at the dyno told me that i should tune my car, that way i can fix my ignition(which they already did by retarding* it 2 degrees, i gain 8hp) and also my air/fuel ratio. they told me to get an apexi e-manage or any e- manage. the last owner of my 240 who put the chip in, sent the computer to JET and they tuned it. the last owner also sent them the list of mods he did to the car. so eeproms is good? is it a e-manage or something? how much?thanks for the replies guys.

[S13FASTBACKSR]

eprom is a rom tune which is basically what you have right now..its a retuned/reflashed computer pretty much what jet did for you..by the way a tune doesnt give you your horsepower. dont get me wrong it does but its not the main source of where the hp comes from..a good tune will give you more hp over a crappy tune because it coordinates better with your upgrades..but your upgrades are what gives you most of your hp. how much hp did you get from all of your upgrades and what were you expecting?

[neverlift]

Nissan factory code is crap for performance in the U.S.,its for economy and emisions. Even the 240sx has crap for tune. I would say that the tune I have now is good for me for about 10whp or its just feels that much stronger as a whole. I will agree with bolt ons is what adds power, but the tune is what will decide if you get all the power from those parts you put on. Again JET's tune is not specific to your car just your mods, which will give everyone different gains. Like I said man did they take the car and tune it or just tune the ecu without dynoing the car? NO, they did not! JET did a bad tune if retarding the timing helped hp. With an ecu tune you leave timing stock 15* bc the ecu does the timing now to what you made it . fastbacksr I tend to disagree that you cant get gains from just the ecu tune. I think plenty of people have done just ecu tuning and gained hp and trq. Like I said stock tune was to please the U.S. federal emission laws of the time, not for power hungry fools like us.

[driftfreek]

i was expecting what pdm showed in their website 163whp (http://www.pdm-racing.com/products/DOHC_stage2.html) which they dyno'd a car with the same mods as i do. im thinking they probably got more hp than i did because they tuned it better. i understand what u guys say about how the ecu tune helps you get all the hp outta your upgrades, and that's what i need, i think. so how can i fix my problem, seriously guys. im learning so please understand.thanks for the help again. keep posting please.

[neverlift]

Like I tried to tell you man, they tune your ecu for mods, not your engine with the mods on it. You need to understand that pdm worked on maybe 5 really good engines(great shape) and probably averaged the results, so if your car is in worse shape it will be lower hp#. Your trans might be worn out more or even your rearend could have lost some power, not as much as you lost but some. All engines are unique,as in the guy who owned the car before, doing or not doing his oil and plugs and wires. Is your car up to date with its tune up and oil change. Is your maf dirty? What I'm getting at is the car should be in decent shape before mods. Comp. test? Even little sensors are so important, like coolant temp(not dash temp) sens. Did the dyno use a wideband to monitor your air/fuel ratio?, if so post that so we can see if its in the power ratio.

i guess i made a double standard what i said was...."by the way a tune doesnt give you your horsepower. dont get me wrong it does but its not the main source of where the hp comes from..a good tune will give you more hp over a crappy tune because it coordinates better with your upgrades..but your upgrades are what gives you most of your hp."

what i meant was yes your tune does give you hp but not the main source..most of your hp comes from your upgrades but in your situation driftfreek you are not getting the hp #'s you expected like pdm did b/c your tune is not as good as pdms.

[neverlift]

fastbacksr I got you man. Just dont want people to think stock tune is as good as it could have been.(performance wise). i also agree about driftfreeks tune being crap. Retarding timing usually gains torque and lose hp up top. PDM probably put in as much time with the tune as the cams. He has good comp at 173 across the board, but something is lacking. How is your coil? btw get that a/f ratio chart posted so we can take a look

[driftfreek]

my car is up to date with oil. the coil is good too. i agree with s13fastback about their car being better than mine( if thats the reason why im losing hp).whats btw?whats maf?and i dont know how to post the dyno sheet to show you guys my results?

[neverlift]

btw= by the waymaf=mass air flow It does sound like somethings afoot with your car. Hows the clutch? Ever changed diff fluid? What size rims tires? They wont account for all the power you are missing. The clutch could lose you a nice bit by itself. Your dyno shows 140 ish so you only lost like 23 somewhere. here is your dyno chart , to post a pic off your pc you need to right click and edit, make the pic 500000 bytes or less playa, or if its on the web hit img when you are posting and drop the link in between the img and symbols on both ends.

[driftfreek]

the clutch is good. transmission good. ionno bout the diff fluid. my rims are 215/45 17in. is it a good idea to go to the junkyard and get a stock ecu and then get a piggy back? it sounds like a good idea, but the stock ecu wouldnt work with the pdm cams right, since its a stock ecu?it'll run like sh**.can i get a piggy back for a stock ecu, or do i need an upgraded ecu to be able to get a piggy back?

[neverlift]

thats what I'm thinking maybe you only have a stock or stockish tune. You could use a piggy back with either ecu, and a slew of differentr cars too. But for that price you could get a megasquirt. A piggy back is to avoid getting an ecu tune or perfect the ok tune say a company like jet would put out. It is a good investment if you like on the fly testing which they dont encourage.

Retarding ignition timing isn't good for anything, anywhere. Unless of course your ignition is already over-advanced.

[neverlift]

adjusting timing can more or less move some of the power band, typically in older non ecu controlled cars. I would only tell a sohc ka to set at stock b/c it already advances into 60* in some areas. I was onlyy letting him know if he retarded timing it was not at stock or to far past stock.

[driftfreek]

my motor is ka24de dohc by the way. if guys didnt know, just letting u know. so i should go ahead n get a piggy back right?

[S13FASTBACKSR]

yes i think a piggy back is a good idea in your situation..ive never tuned with a piggyback though or know anybody who did but i would imagine its somewhat frustrating..but you gotta do what you gotta do..but im probably wrong anyways..good luck i say go with the piggyback

[neverlift]

did you even go to http://www.hybridka.com ? It will give you all the info to decide. I dont like to say go do this or that, but offer advice.

With that said, I too would say get yourself a piggyback. It will only control fuel but with no turbo or aparent plans you would not need to retard for boost or add tons of fuel up top. A piggyback only alows for IIRC 50% +/- . But once again I say that a full stand alone ecu like megasquirt is about 50~100$ more than a piggyback, with way more tuning capabilities.

[driftfreek]

i guess then ill just go with megaskirt. sounds good to me. if i buy it, is there a way to install it myself or do i need someone to do it? do i also need a kit to install it or something like that, you know how greddy requieres a kit n stuff? do i need that or not?

[neverlift]

I hooked you up with links on hybridka .

[driftfreek]

the page is not working anymore, ionno y. it says page cant be displayed.

[neverlift]

yeah I hope they didnt pull the plug on it. Give it a day or so maybe they are just under construction or upgrade.

[driftfreek]

i got to the homepage of hybridka but thats it, it doesnt let me go any further.. wth!!! wat happened to it neverlift?

[neverlift]

I'm not sure man, it was fine yesterday and last night. Are you logged in?

[spank044]

Hey neverlift,

Not trying to steal the thread, but the time has come for me to upgrade my ecu.Whats the big diff between the bikirom daughterboard and the megasquirt ecu?

I don't know much about the Megasquirt, but from what i've read the bikirom is very easy to install and use. My last car was a Honda and that was real easy to tune. My s13 not so much, so thats why I like the looks of the Bikirom, but I want to know what the megasquirt is and how user friendly it is. I've read there forums and faq's, understand some and some went over my head. So can I get a little help.

[neverlift]

I have not looked into biki rom yet, but have read everything and talked to probably everyone at diyautotune.com about megasquirt. I would say go with it for the wiring ease(so much cleaner engine bay when done correct), and you can get the unassembled unit for like 150. Its map based instead of maf. I believe it has more features being a full stand alone. But I said I dont know much about the biki. I have read good and bad about both.

What year is you car? if 89-90 you could get away with just burner,chip,zif,and time. My method and love it.

[driftfreek]

i saw the megaskirt ecu website or this site about megaskirt and there are different things and components and i dont know what they mean. neverlift, can u tell me, if i wud to get it now, which parts or components shud i get from megaskirt for my 240 and around how much wud the total be?thanks
