Biki anyone?

[docrice]

Hey, is anyone here currently using the new Mega Biki hardware? I know i recognized some of the names on there from our forum (jeff240sx, etc). I know it hasn't been out long, but it sounds like a lot of people on their forum have it up and running. Just wanted to know what people's thoughts were on it, likes/dislikes, worth the money, etc. It's about the top of my list for fuel management right now, just wanted to hear a few reviews from people who are not biased. I'm probably gonna go ahead and order it, just looking for some reassurance i guess :loco: .

[NismoSilvia270R]

billklinevt uses it. adn i will be using it.

that thing is a piece of art.

IMO its worth the money and more. c

edit: i cant read

[theicecreamdan]

what's biki?

[docrice]

The Biki Mega is basically a new daughterboard that adds onto the factory ECU and has a reflashable ROM. In short, it lets you use a USB hookup and a laptop to view consult data and tweak factory maps as much as you want, but since it uses the reflashable ROM you don't need to burn a new chip and put it in every time: you just download the new program to it every time you make a change. It's very much like the I/O sim boards (Motorola HC12 based for any electronics guys) I use at the college. Easy to reprogram, very cheap (~$260 shipped I believe) and does everything you'd do with a Emanage Ultimate or similar.

fo shizzle? LOL! :)
that sounds great!

Plz PM me a URL if you could, sounds like a great product that, at the very least, would drive down the cost of competing hardware

[infinitexsound]

sounds like the bikirom stuff..yeah well worth the money..

[NemeGuero]

I'm on KA-T.org and I'm waiting for them to get that group buy going...
I can't wait to start messing with that stuff. Hopefully Jeff and Billklinevt will share some of their maps and stuff with us.... :D

[docrice]

I'm probably going to order it tonight. still want to hear comments on it if anyone's got some.

[BillKlineVT]

I definitely recommend it. Though there is a learning curve to tuning the fuel maps for s14 KA's (r34 style data, I pretty much have it figured out), you can't beat the ease of tuning with this board. This board works for pretty much every nissan that has a header in the ecu... s13 KA, s14 KA, s13 SR (red and black top), s14 SR, s15 SR, NA SR's, forget which RB's, even the EEPROM based ones like CA's, some RB's, and KA-E's will have an adapter (still being tested) so it will work with those ecus too. If I had to burn a chip every time I made a change to one of the maps, I would have gotten verrrry frustrated. But, instead, I just upload the new map via usb cable with my laptop in about 30 seconds (I think he's working on making that faster). The maptrace feature is AWESOME, and no other setup for this price does that. He even has circle gauges in there for RPM and speed as well as bar graphs for things like injector duty cycle, AFM %, TPS, o2 voltage, etc etc. The software is still in development, but it is very usable already. There is even a simple datalog feature that allows you to go through the logged data via scroll bar right now. I speak to Lucas (BadBiki) regularly and he said the external switch funcitonality (flatshifting and 2-step here we come), wideband logging, as well as many more features will be released soon via software update. Other features such as external outputs (turn on e-fans or whatever at a certain temp, etc), Boost controller/Turbo Timer/Map sensor will all be "unlocked" via firmware updates in the future and some will require other harnesses or "looms" to make them functional, as well as a code to unlock their functionality in the software.

The website is www.bikirom.com if anyone didnt know... and I'm glad people are finally catching on to this... check out the forum on the site if you have questions. I'm not affiliated with Bikirom but I just promote it as much as I can because its such a great deal and very easy to use.

[docrice]

Bill, you are the man...that's exactly what i wanted to hear. I'm as excited as the upcoming features as i am the current setup...time for some paypallin'...

[NemeGuero]

can't wait for mine.. but I'm a cheap-ass so I'm still gonna wait for the group buy.. hehe

So Bill... you said on KA-T you were gonna post a write-up.. that still in the works?

[BillKlineVT]

Yeah it's still in the works... I have this one big project left to finish by Monday then hopefully I'll have time to finish tuning and do a write-up. I'll post it on all the forums I can think of once it's written

[NemeGuero]

DOPE!! Karma will come around Bill... karma..

[docrice]

def. looking forward to that writeup Bill. In the meantime, the best i can do is sit and anxiously await the arrival of my board.

Also, what are you using to tune? i'm probably gonna pick up a wideband with a datalogger since dyno time is not cheap...we'll have to see.

[NemeGuero]

PLX-M300 baby.. oh yeah

[docrice]

OK bad news...even though the site said he had it working for the 96 ecu, he doesn't. He emailed me and said it's close, but the car still won't run right and there's obviously no ETA on how soon it will work since he's so busy with all the other features plus school and whatnot. I'm going to have him cancel the order for now, but I am going to get it once he does get the thing working for the OBDII ecu. Life is tough...

[kaje36]

he curently has my 96 ecu and is testing useing that. and had some good news this morning. he made alot of progress, give it like a week for him to try a few more things.

[docrice]

well he suggested that i just get a refund for now unless i wanted to source a 95 ecu to use it with...Once he gets it working I'll be reordering it. It sounds like he's pretty close, hopefully there will be good news sometime soon. On the plus side, I don't really need this right away, the car's about to get garaged for the winter, so if its not done within a couple weeks i won't need it til about jan-feb (although i wanted to do a track event at VIR in feb so it would be nice to have)....

[NemeGuero]

yah, why couldn't you just run an OBD1 ECU in your OBD2? they're cheap and easy to find.. I picked one up for $40

[go240]

this is what i'm looking to get. is it easy enough to use that my local dyno guys could tune it without any prior experience?

[NemeGuero]

its blank, you have to create all the timing maps, fuel maps, and each of those under different boost conditions (if you're turbo that is..)

wait for Bill's write-up and read it.. if it seems like something you understand and can deal with.. then go for it. it does take a lot of time and WORK

[docrice]

so it doesn't have a base map built into it for stock settings? guess it'll go on when the car is garaged for the winter then... as far as getting another ECU, don't really feel like spending the time/money, esp. since i'm not in a huge rush...already have 2 OBDII ecu's anyway haha....

[NemeGuero]

lol, yah, i got an OBD2 auto, OBD2 manual, OBD1, and even an s13 ECU I think..lol
I'm a collecter. ;)..

no there aren't any base-maps, but you can find them. but if you're turbo, they'll only work for pre-boosted conditions.

Also, what do you think the benefit (other than not buying another ECU) is of running an OBD2 ECU? 'cuz I'm using an OBD1 in my 97 and I dont see any differences.. Unless I'm missing something, but I dont even have EGR so there aren't too many differences. Coolant temp sensor, distributor sensor, CPS.. EGR duh.. but mine runs fine.

[kaje36]

its easy to pull the base map right off the stock ECU, I did that back before I sent my ECU off to badbiki. the software comes with a few base maps right now. so its not realy something to worry about.

the reson at least for me running OBDII is its required to scan for codes as part of state inspection.

[docrice]

It would allow me to get rid of some emissions crap, but I have to leave that stuff hooked up anyways for state inspections...i imagine if i can find one i'd get it, but like i said, no hurry, no money, etc...

[NemeGuero]

you need an OBD2 ecu TO get rid of emissions?? I dont see how that makes sense. OBD2 has more EGR crap..

[NismoSilvia270R]

no there aren't any base-maps, but you can find them. but if you're turbo, they'll only work for pre-boosted conditions.

they say for s13s, the sr20det maps are 'close' enough to start a ka-t map..

[doug200t]

so is there any HEX we need to convert when typing in numbers in to it? or can we just go at 1k rpm put -8 fuel and 1200rmp -9 fuel stuf like that? i dont have to go Ae0 equals -9

[docrice]

Sorry I didnt clarify, the OBD1 ecu would let me ditch some emissions shit... although i don't know how much of a difference there is aside from the stupid rear 02 sensor that has to be on the car (working or not, but visibly there) for my inspection...just like the cat...if it looks ok, then PA says alright...but whatever.

99% of the hex stuff has already been converted. the only think I have found that you need hex for, is locating things in the rom file when you want to add a table that isnt already there.

its a little more complex then just -8, -9. Are ECU's are set to go by A/F so you would get to the right table with everything set right and plug in.. 11.2,... 14.5 stuff like that. and the car would try to run a 11.2:1 fuel mixture.

gotcha, I'm using an OBD1 on my OBD2 w/o any issues.. not even a CEL since I dont have any EGR.. only the damn airbag light (new steering wheel)

[Xren17]

How did you manage to run a OBD1 ECU? Did you make a OBD2 to OBD1 harness or did you just replace the entire wiring harness?

Thanks,
-Ren

[NemeGuero]

no, I just removed my EGR entirely and plugged in an early model s14 ECU. I did it 'cuz I wanted a manual ECU after my swap about 6 months ago. Everything works fine..

[kaje36]

Bill kline is running a 95 ECU in his 97, JWT has a writeup on the wires to swap, I think its only 4 wires. but it will even run without thows wires swaped

[NemeGuero]

as me for example.. haha, the only wire differences I think are evap(EGR), rear 02, AC signal, and some other stuff that I don't use.. therefore.. no problem without switching the wires

[NemeGuero]

woops, the last wire is the FICD... which might explain why my car idles like shiatt lol.
gonna get that handled.

[Xren17]

Awesome, thanks for the link. I hadn't realized that the S14 OBD1 had the same plug as the OBD2.

[NemeGuero]

no prob. yah, only diff is those 4 wires. if you don't have EGR or AC then all you need to switch is the FICD wire for your idle solenoid
