Just wondering if there are any plans to use the eld wideband input to be able to get more of the functions that the rsx guys have, like lean out protection?

Is it even possible?

Thanks
Ed

The issue is that there is very little room left in the PRA rom.

Ok.
I'm not familiar at all with roms. Can the s2000 kpro use a prb kal if we use an aftermarket wideband as the primary o2 wideband like the rsx? If not, why? From what I remember there was a guy who successfully used a wideband to get full functionality by rewiring his kpro. Is it possible to offer this in the s2000 kpro from Hondata?

Also if we are limited to using pra are there any plans to do what I was asking about in the original post & or is it possible? It's just kind of a bummer that the s2000 kpro is the one of the most expensive kpros & it doesn't have all the features of the rsx. I realize this is due to the s2000 using a 0-1 volt narrowband.
I'm just wondering if there are any solutions out there to get us all the functionality of the rsx kpro without having to hack up our kpro ecu ourselves?

Thanks,

Are there any plans to try to get the S2000 Kpro all the functions of the rsx?

As above, the PRA has very limited internal memory space.

If you have some electrical expertise and wish to convert to a wideband and the PRB calibration, it is possible, as we added the wideband pins to the E connector. However, this is something we do not support.

E4 IGP
E5 IGP
E6 (RSX A6) PO2+
E7 (RSX A16) PO2-
E8 (RSX A1) P02HTC
E9 (RSX A22) P02H+
E10 (RSX E8) P02HTCR
E11 SG
E12 SG
E13 ELD

Is this for teh dual adapter or the 00-05 model. The 00-05 model doesn't have an E connector.

00-05 model

Well elaboration would be a pain wouldn't it. Would you care to elaborate on where the E connector is on the back of the ECU. There are only 4 slots. A-D on the 00-05 KPRO. The D connector has the six wires of the cam/crank sensors in the first positions..trying to figure how you can have two different sensors signals on the same positions..so where did the E connector go?

He meant the D connector.

Would you care to share the entire pinout of teh S2000 ECU? The ELD input is supposed to be on A30

Hondata's post says it is on E13 which you are saying is D13, how is it on both pins?

I am just trying to get more information so I can help people get the RSX functionality from this ECU. I happen to mod them so that they can use the RSX wideband, but it is a lot of work and can damage the ECU if not very careful. Being able to use the D connector would be a great feature and would be very helpful.

The pinout for the OEM connectors is unchanged from a factory S2000. You can look up this pinout in a Helms manual. We add a subharness for the new sensors installed for the exhaust cam and the crank.

Details on the S2000 K-Pro inputs and outputs can be found at http://www.hondata.com/help/kmanager/ecuconnectors.htm

I know you are a busy person and realizing the entire conversation put together is why I have asked ths question. I meant the pinout for connector D which Hondata just said has extra pins that are not in the link you pasted.

BTW, I do have the helms manual for the ECU pinouts on the S2000 and I know that not every pin functions on the ECU which is why the airpump no longer works, this is the information I am looking for.

Why did the S2000 Kpro come with the PRA cal instead of the PRB cal & just use the rsx wideband originally?
Was it for cost so people didn't have to buy the rsx wideband? If so most people have to buy a wideband & controller anyway (spend the same $) & then don't have the lean protection.

Since we know it's possible to convert to the PRB cal & use the rsx factory O2 could you start offering it as an option & or upgrade people who already bought one?
I think many people are very weary of hacking on their $2000 ecu & doing something that Hondata doesn't support.
