Hondata

If I have the receipt and verification from your distributor/dealer that this is their unit then would I be able to upgrade the unit? Apparently there is an issue here that occurred before I obtained the unit and therefore out of my control.

Well I can assure you it's not. As a matter of fact I've got my receipt and the shop that I bought it from is very reputable (one of your dealers). Now back to the more important matter at hand, is there an upgrade that can be done to the kpro so that I can datalog?

i do not have a bar code on the kpro board. there is no specific number onn the board. i have a serial # for ecu which is in an above post.

serial # 37820 prb a05

2068-501089 0j25

I have a k-pro setup ecu prb a05, # on kpro board is E199143 94V-0 (no clue what this means)

setup is k20head/k24

I am unable to datalog unless I do it manually. If I set the datalog parameters for "based on engine parameters" and upload this to the ecu, when I check the ecu, it never uploads the ...

Guys, I figured out the problem :D . I rechecked all of my wiring as well as the plugins that I tapped into. In actuality I tapped into d14 (5 from the wrong end) as opposed to d10 counting 5 from the correct end. So the d14 is the heated o2 sensor signal. When I checked my voltage in the eld ...

here is the calibration

OK, I pulled the ecu and checked. It does have the r136 and r138 resistors. I removed these. Now the ELD is reading 0.02. This is the same reading with the ELD disabled or enabled.

I checked the voltage at the output from the PLX and it reads a varying volts depending on how the accelerator is ...

are these found in obd 1 ecu's as well. i have a p72.

Update.

I hooked up a known functioning wideband (innovate handheld obc 2 scanner and wideband o2 sensor) and it read completely different numbers to the PLX. I adjusted the voltage offset so that it read exactly the same numbers as the innovate. I then varied the rpm's but there was not ...

actually i do not have a wideband gauge, i was going to keep my laptop for tuning purposes. i do have a separate wideband (innovate handheld unit) that i can use to calibrate. i am just hoping that all else equal, the plx is functioning properly. any other suggestions?

OK, so i put it into closed loop. Do I use the wideband for closed loop too? I removed the narrow band sensor as well.

Also what do I set voltage offset to? You can change it to read whatever you want, so how do I know if my wideband is working? Can I set it to 20 AFR with the car cold and off? I ...

Setup

p72 obd1 ecu with s300 in 1990 crx. plx is in d10 slot of hondata and input from car harness is cut. running b20-vtec setup.

calibration included

btw, this is just to get the car running and to get tuned later input is appreciated. you can pm me with any recommendations.

thanks
