i need some opinions on which management choices i have for a turbocharged ls/vtec w/obd-o. i know the new hondata only cater's to obd-1 same w/aem ems. without going to something as drastic as haltech/accel dfi etc... or race specific stand-alone. what else can i use? am i limited to zdyne? i am also thinking maybe sds? anyhelp would be cool, thanks

Hondata works for OBD-0.
PW0 and PR3.

You just use the 'old' stuff, stage 2,3,4. All the same 'features' of the
current s200 just not as polished.

Why not use the Z-dyne ?, I have put it on many cars, supercharged and turbo ( Inc my own) and it has been great. The tunes that come with it are so close you will be up and running in 5 mins!

speeddave

does both the early hondata's and the zdyne require both o2 sensors and the knock sensor? thanks for the help guys!

You can disable the knock sensor in an ECU by wiring a 1K resistor to ground on the knock sensor input wire.

Zdyne's only need one 02 sensor. Not sure about the Hondata.

I'm going to do an Autronic unit in my CRX.

Hondata needs what the stock ECU needs...
It is not a different ecu it IS your stock ecu with a 'new' chip.

But you can dis-able the O2 sensors and run open loop if you need.

If I were you I'd go full standalone. I'm currently using the DTA unit. Wiring wouldn't be that hard to do and the price is very reasonable. I can get a unit for about $1300 CDN.

How much hp you shooting for?
What about the hack if you are shooting for 300 or less hp?

You don't HAVE to disable it, right?
What's the advantage?
TIA

Just like the 88-91 d-series computers, it only uses one O2 sensor for open-loop control. You only have to use one O2 sensor, but in the Zdyne you can disable the open-loop. Diasbling the o2 sensors function allows you to run off the maps in the ECU instead of relying on the o2 sensors input.

so to run one of the older hondata obd-0 programs...what exactly do you need, one of those two ecu's listed....and what else?

speeddave

where would i find the dta unit? how bout hooking a fellow canadian up

i'm shooting for the 300-350hp range, i was thinking of the hack, but i was also interested in the smc, but i still have the hurdle of the 2nd o2 sensor and the knock sensor to get over with the pr3 ecu.

speeddave

i just wanted to move this up to get some more input

Jefnes

and a GM 3 bar map sensor if you want to run more than 10-11 psi.

That's it !!!

i have a d16a6....do those ecu's plug right in?
