JIM WOLF ECU questions

[D1 guy]

Im sure this is already posted somewhere, but I couldnt find it. Somebody tell me if Im understanding this correctly. The Jim Wolf ecu is a programmed ecu for mafs and injectors. If I have something like 550cc injectors with a z32 maf then the programmed ecu will make the car seem like it came from the factory that way. Then all I have to do is turn up the boost and Im done. Just like with the factory setup, everything will compensate for itself up to injector maximazation. Is this correct or am I completely wrong? Please help b/c im seriously considering ordering one of these. Thanks

what you assumed is correct, it will not only give you new fuel maps, but will also give you new timing maps suited for turbo charging

I would like to ask something real quick. I have heard about using the JWT ecu and I have even looked for it on their website but they really dont give any details about it. So basicly do they make the ecu only for the DE or do they make it for the E as well? Anyone got a link to the ecu being discussed in this thread? Any help would be awesome. Thanks.

Im sure they do. The E is the simplest of all KA ECU's to mod. Almost brain-dead simple, as it requires no daughterboard.

There's a complete list of the ecu's they sell listed on the website. It's broken down by model and motor.

true, the 89/90 ecus just require a zif socket for like 3 bucks lol, but if your considering going to jim wolf, consider again... its WAY expensive, try http://www.bikirom.com the megaboard isnt out yet, but will be in a matter of probably a week or two... and will be ~150 bucks

Thats what Im going to do for my emulator set up. From the looks of it you should be able to run a single emulator instead of dual emulators.

Actually Im buying the LM-1 first, then that.

Good link. Interesting stuff

[hysteria]

i just browsed over that website you provided... very interesting... but do you know if they do/will offer anything for the ka24de? this is something i would really be interested in purchasing as i feel, like you said, that jwt is a little over priced for what it is. I would completely be interested in learning about this and then doing it myself. that is of course if they offer some compatable solution for the ka24de (i have all 1992 electonics controls and a 95 block and head, so i would be looking at a 1992 ka24de solution).

Heres a break down of what you need to know.

B13's and S13's share the EXACT same motherboard. What this means is that your ECU uses the EXACT same traces to get its information from the built in memory as the B13 SR's and S13 SR's. So, the product that your looking at on biki's site will work for the OBDI KA24DE (91-93).

Im using a B13 daughterboard on my KA and it works fine....Cost me $100 and now I have a fully reprogramalbe ECU. Dont forget though that you will also need an EPROM burner. Mine was $150, but, mine is also overkill. You can get a reputable burner for like $85 (Willems).

S14's use a different board, so its highly unlikely that this would work on them.

All said and done, modding your stock ECU with a daughterboad (exactly what JWT does only they use a single 16bit chip with scrambled code, which I have and is de-scrambled) will cost you about the same as a full E-Manage set up, or a plug and play JWT set up.

Cost break down:

$100 for a DB, $85 for a burner, $350+ for a wideband O2 <--because tuning with out one is pointless.

The beauty of it is that you will NEVER have any downtime, shipping costs, turn around, or, pay for an miscelaneous reprograming due to part upgrades like MAF/injectors/revlimit changes etc....

That sounds super sweet. I've asked a few questions over at their forum regarding sohc & automatic transmission & base maps.

What you need to do now JRL is to write a start up tutorial: "From getting the pieces in the mail to running your hacked ecu and tuning w/ the bikir0m" - that would be mad awesome if you made something like that

[hysteria]

i know biki would probably help a lot with all of that info but you posting up a write up of what you have done, learned, etc would be soo damn awesome. this looks like a great investment. please do a write up

[JRL]

i please do a write up

I can do a write up, thats not a problem.

Theres several other boards available, most of which are cheaper than Biki's newest boad, but, the Biki board looks uber more versatile than the others. Seriously, that guy and the guy I bought my board from are pure genius. They could shed a TON more light on this subject than I could.

But, Ill start a write up, and hopefully the educated lurkers will chime in.

EDIT: It may take a while before I can post it though. Its just a lot of info.

[hysteria]

thanks a lot, it's really appreciated.

also i found this site for tuning... http://forum.ztechz.net/

http://forum.ztechz.net

Its a good site, Ive learned a lot from it.....still havent registered an account there though.

Do a screen name search in the 240SX section of that site for a guy named Calum. He knows his stuff. Im currently using his board.

Heres another cool site that you may be interested in. Its for a 300ZX, BUT, it gives you all the basics you need to know in terms of reading code and tuning your ecu. Although our boards require a more complicated chip set up than the 300ZX example on that site.

[hysteria]

yeah i was reading some stuff on http://ztechz.net

very helpful and informative. i don't have/probably never will have the equipment to do all the precision soldering required but i know good places that could do everything for me and for not much money... especially if i brought it to them opened up and ready to go. they were talking about a sucker and all of the little stuff costing an arm and a leg on the site/forum.

i like the idea of the eprom socket, so i could just swap out eproms ina few seconds if i wanted a different fuel curve. man this stuff is awesome. i have been introduced to something i was looking for for a long time, but just didn't know where/what to look for. thanks a lot. i'll be looking for more info/ a write up, and probably be reading a bunch once school is out. i would like to aim at doing this over the summer... that would be friggin awesome.

i found that link you just posted by going to http://ztechz.net and it's exactly the same site... i had been reading the ecu getting started stuff and just going through and understanding everything. do you generally just download curves from people who have already made them, or do you make your own? how sweet it would be to sit with a computer in my car and tune my eprom as the car is running. oh boy i feel like fast and the furious! lol

[WDRacing]

Make a new thread on this, that way our members don't just think it's another JWT thread. The Biki has my attention.

[hysteria]

i made a new thread...

zer...d=170

edit it/add more as you see fit... jrl if/when you get the write up done, maybe you could post it up there... thanks again for doing this.

in regards to the JWT ecu, does having a obII ecu retuned automatically set off the check engine light?

[hysteria]

why would it? if it's tuned to handle new variables and constants and those things are coming through correctly, there should be no reason for the engine light to go off

[DRIFTEADOR]

in regards to the JWT ecu, does having a obII ecu retuned automatically set off the check engine light?

They don't use a obd2 ecu though, do they? as far as i know, they use a obd1 w/ a conversion harness.
