I was wondering if using an EEPROM programmer would be a good alternative to spending loads of money on something like a powerFC or AEM EMS, etc...

Just curious, please dont flame me if I'm an idiot and it's stupid...

ummm...i use it!

 

well then... if u use it I HAFTA get one ;-)

 

That's what Hondata and Techtom are.

 

ECU reprogromming is just as capable of properly running a finely tuned motor and Hondata or most other high dollar EMS's. The major difference is in the ease of use and features. EPROM programming is not done in real time, meaning you make a pass, adjust fuel and timing or other corrections and burn a new chip and run again. Hondata, allows you to program in realtime, when the motor is up and running on the dyno or driving around, etc. So you can more easily and more quickly dial in the fuel and timing curves. Similarly with AEM or Power FC. AEM's is nice in that you can have it use a wide band or narrow band O2 to self-dialin the fuel curve, then you can simply tweak it. If you are a true DIYer, go for EPROM programming. I am not sure how I feel about Hondata personally. Its a nice system, don't get me wrong, but I like to be able to personally do my own tuning and in order to do that with Hondata you get gouged with all the extra crap, so you end up paying nearly $1000. At that price I would almost rather have a AEM or Power FC. If you have your car modified like you like it, and don't plan to tune it yourself, then Hondata is a nice choice, because you can purchase the S200 or S100 and have it tuned for $600-$900, and call it a day. But my philosophy is get control of the motor first, then build it. This approach requires tuning with each modification along the way. Just some things to think about. Who's tuning? Is the motor already complete/modified? If not, how many iterations of mods do you plan?

 

motor's darn near done...

LS/VTEC, 12:1 compression JE pistons, Eagle rods, B16 head w/ ITR valvesprings and stock b16 cams (Skunk2 Stage 2 and Ferrea valvesprings whenever I get headbolts and a new head gasket)
CM stage 3 clutch,
All the bolt-ons, in a 2180 lb 93 Integra.

It has a P28 in it with a "skunk2" chip in it which I think is possibly a SOHC chip in there. Ebay chips are gay.

That's about it as far as the motor's build is concerned.

 

If motor is complete, then I would consider Hondata with the shop tuning it.

 

the shop? If you're referring to "the shop" that built the motor, that'd be me. ;-) But I was looking at Hondata and it seems like they just do the same things everyone at PGMFI.org is doing but "professionally" which is cool... It's just that I'm all about saving some money. ;-)

I'll definitely look at it more though... On prob. is that I'd hafta buy the whole kit including EEPROM programmer, datalogger, etc. because nobody around here can tune Hondata.

If anybody in the Charleston, SC area tunes Hondata S200 and has the datalogger and EEPROM programmer, etc. let me know.

Thanks for the responses guys.

If you have to buy all the extra junk, don't buy Hondata. Not worth it if you have to buy all the tuning software and hardware for one application. Pay the extra and get AEM or Power FC or TEC or something similar. Hondata is simply not worth it if you have to buy all the extras to tune it yourself.

If you are a true DIYer. Go for the self programming with CROM or UBERDATA, etc. You will learn alot more. Just play conservative.

 

Cool... Last night I ordered an EEPROM programmer and a chip to get me started... it's one of the eraseable ones so u know.

pgmfi.org is a good resource. Blundar is the admin of that site and alot of cool stuff has come from them like the romeditor called "Crome".

 

Indeed... I have been playing around with crome and roms and stuff, but I dont know where to find more roms, or if I could find some OBD2 ones and convert them to OBD1... Not to mention pgmfi.org is the first and only site I've seen on the subject...

Anybody else wanna shoot me some links, etc. let me know.

that actually came from John

but yeah, Crome is awesome...l've been using it with my old 191whp ITR swap...and it's going to be running my new engine build that should be 225whp ish.....

it's basically hondata, they share 98% of hte same code.....and it's a HELL of a lot cheaper

PM J.Davis if you'd like ot be educated about the stuff....he's been doing it as long as anyone else...and he does my chipping as well

 

Thanks...

Who's J.Davis?

 

he's Joseph Davis...
a good friend of mine

he's been around since the beginning....and has had more time tuning cars with Uberdata than anyone else...and also did all the beta testing.
he's also good friends With Dave Blundar (who i was lucky enough to meet a couple months ago when Joseph and I took a trip up to his place)

he knows hist stuff...and has helped me immensly

Nope, since RTP came along we at pgmfi.org are a tune on the fly institution.

Actually, that is untrue. Last I knew, Hyundaidata still required an Xtronics ROMulator, and you had to power down the car to reflash it. It's a hassle of extra wires (greatly reduced since the blue interface box was stuck on chip inside the Hondata S100/200), complexity, and time wasted. Did I mention you paid for Hondata?

Translation: I haven't killed him yet. I *did* shoot him last Thanksgiving, but it was with a paintball gun.

I'm an unfamiliar face in this forum because I usually terrorize HT's Farced Induction Forum. Lotsa those guys think everything has to cost a million dollars, it's a full time job keeping it real.

FYI, I'm sending Blake an RTP board and he's going to code RTP support into Uberdata. You'll probably be an Uberdata boy in the next month or two.

 

back to uberdata i go!

but you better hurry...i'm off to marks in about 2 weeks

but, if i have to..i can always go back

Kinda correct and kinda incorrect. You have to power down to flash the initial roms, but then when changing the parameters, you can do it real time with romulator. I do this when tunning my car.
JD how do you tune realtime with chrome and how do you datalog without have a box to connect to?

 

the RTP and data logging aren't public yet...

I hope to have mine as soon as joseph can set me up....

btw Joey....be ready...Eugene and I are coming up there next week sometime

 

RTP is public, or as public as anything pgmfi.org gets. If you don't go there, you probably don't know. Dave's been selling RTP boards and RTP boards + parts kits off pgmfi.org for a couple months now.

Datalogging is pretty simple; you just have to knock the RS-485 baud rate down to something that can be handled by a computer's serial port (this is done on the code side) and use a TTL-serial converter ($17 kit) to make the ECU and computer you hook it to physically communicate.

 

and i stand corrected

but joey...do you have any of hte stuff ready for my car? i might can get you soem magizene mention with a pgmfi.org hit as well

 

feel free to ***** up my post. lol.

j/k I dont care... I got some info, that was the point.

 

Hey, you're free to ***** up and hijack any of my threads

Seriously, I get really excited about pgmfi.org stuff... lotsa goodies, all free, power to the people.

 

look at j.davis acting like he know's...

 

I'm excited about pgmfi.org stuff too its just that there's a lot I dont understand and the forums dont have much info on what exactly I need to do to make what I want happen...

I can do the maps, no prob, need some help with ignitino tho. fuel I can take care of I think... but then I wanna do FTL as well as Datalogging and/or RTP... Which there's not much info on the way to make FTL or RTP happen on a p28 running a DOHC engine.
