OBD0 ECU chipping.

[GU357]

Anyone tried these chips?

Im thinking of getting one for my PWO OBD0 b16 EG.

wondering which to get, KS, Mugen, Spoon, Mines??
want good rev pull!

they are all BS lol dont bother

[GU357]

you realise, the difference between a spoon ecu and a normal ecu is this right?
and they allow you to absolutely change everything about the ecu.
but these are preset; modified timing, afr, vetec engagement, launch control 4000rpm, cel light becomes shift indicator, blocks off 2nd o2 sensor, kick sensor, rev limiter can be changed, no speed governer.
ive heard good things about them i really want to hear from someone with knowledge or experience.
this isnt the average thing you see that they make for any old car like that so called ecu chip for obd2 cars which is just a thing to tell the car their is more air.

these chips are completely different basemaps

[Scholzey]

the reason they aren't any good is because they are just a general tune. its not specific to your complete setup.

everything may be tunable, but not by you or anyone else after the chip is installed. so when you order it you better have everything perfectly set exactly how your car wants it, because there is no changing it.

but i guess its cheap.

[GU357]

hmm, they are designed for the stock car though with some mods.
so just to "unlock" the engine, so it no longer passes emissions standards but it will make the engine run just a little more freely.

and the chips are editable.
theres a program called turbo edit (and other programs too) that allow you to tune the chip.

with this it means if i were to turbo the car i would have to do obd1 conversion and get a hondata ECU i could just re-edit the chip.

Wouldn't bother personally. I don't see any reason rev'ing a stock B16A to 9,000RPM with OEM camshafts. You won't make any more power that high and it will struggle to get there/put undue strain on your OEM valvetrain. Don't see the point in dropping the VTEC crossover to 4,600, and disabling things like knock sensor and O2 sensor is probably more dangerous than beneficial. OEM idle shouldn't be too much higher/lower than 850 either. If it is then you probably have an issue.

I have a friend who uses a HKS chip on his OBD0 B16A just to remove his speed limiter so he can go 200km+ at Sandown and Phillip Island but otherwise it's got no other purpose. Probably not necessary on most cars.

Tunable ECU for built engines, or just go OEM IMO. Asking for trouble otherwise.

[GU357]

fair enough.

though the reason for removing 2nd O2 sensor is so that the engine only needs one and u can put on aftermarket headers.
and the removal of a knock sensor is because apparantly the KS didnt come with a shielded wire and lots of ppl would pick up KS error codes, just because of interference. and they would then lose power, because the ECU tries to rectify the timing.

also revvin to 9k was so i could accomodate a cam upgrade.
also the redline on that engine is 8k, and the revlimiter is at 8k. so its hard to change at the redline because the limiter just shuts the engine off

edit:
but it sounds like i shouldnt expect much from it. and i take your word because you have quite a bit of tuning experience from what ive read on forums.

[dougie_504]

If you're going cams then get a fully tunable ECU to reap the maximum benefits.

OBD0 B16A (I'm assuming JDM) should redline at 8,200 and cut out at 8,400.

As for the O2 sensor I reckon just buy a good header that comes with a sensor socket.

[GU357]

well if i upgrade for a hondata i will also have to do a obd0-obd1 conversion.
so the header will already have a plug for that. but the chip was so i could not have to do the conversion, and still smack new headers on which have only one o2 sensor.

[dougie_504]

You could try to find an obd0 Hondata

[GU357]

hmm but would be pretty rare, they dont sell them anymore. and i did a qucik ebay search, no results.

[mugen_ctr]

save urself the headache an go obd1 with hondata chip... go hondata S100 or S200 (blue box) is proven to work well in all situations, boost or n/a, Hondata No longer support OBD0 for reasons ive read that it isnt as well refined as OBD1 ecu's, so best to just get jumper harness an go obd1 ecu that suits ur car.

if you go OBD-0 to OBD-1 you will need to change the dizzy aswell dont forget :)

[GU357]

yehp and get a 4wire O2 sensor

[hitoriko]

yehp and get a 4wire O2 sensor

is a 4 wire required?

[curtis265]

another thing is that i don't think anyone can tune a hondata in WA...

Best call up shops and see what sort of options they have for tuning

[GU357]

lol wait for the next honda tuning day, 6months

ohwell i wont be swapping over soon, still have other stuff to worry about, then fix something that is currently doing its job well.

[bboyzell]

Iv got a Socketed PR3 ecu in my ED9 CRX (running a B16A)

Those ebay chips aren't anything special at all! ,Now that i think of it iv got two socketed PR3 ecu's sitting in my shed :/

I purchased a Rom burner too, but have yet to start making my own roms, since i want to get a AFR sensor and gauge installed, so i now that the roms aren't leaning out my engine!

[GU357]

Oh alright.
Did you get a chip that had drag launch? that looks like one of the coolest hings about the chip so far.

[bboyzell]

Looks up a program called BRE (BEN ROM EDITOR)

You can customise the Rom to do a few different things, and yep launch control is there.
Also you can get the CEL on the cluster to act as a Knock Light
Or you can do as iv done to mine and Make the CEL act as a Shift Light (got it set at 7200rpm)

[bboyzell]

Double post :(

[GU357]

yeh ive seen that.
still need to socket mine though.

[sebtoombs]

Socketing is not hard. And like bboyzell said, those chips are nothing special. All honda ecus are basically the same internally, with the differences being in the code. These chips are just an external source for replacement code (a feature that honda incorporated into their original board design). Thats all a 'fancy' hondata is too, except it has a programming interface built in too.

I'm currently in the process of designing my own on-board usb host for real time programming and easy datalogging.

Oh, and if you can't find somebody closer, I can socket the ECU for you. I think it costs about 15 to post an ecu.

[GU357]

alright thanks.

project is on hold at the moment since the car is running well, and its my daily so i cant ship the ecu off.
