Hondata

I see s300 has a MAP sensor in the options available for display which shows "/psi but that doesn't actually count as an accurate vac/boost gauge. does it? Probably not

So if i need to hook up a vac/boost gauge can i get a CAN gauge or some kind of gauge that hooks up to s300 v3 so that the vac ...

I got my hondata display and aem wideband afr gauge to match comrade i have it hooked up exactly like this guide:

and then i had to go to Parameters > Closed loop advanced. And change the voltage afr table to match numbers provided for the aem ...

Install a 2nd bung for the wideband?

Thank you
You mean when i use d10 for wideband, i should leave d14 alone and keep my stock o2 sensor installed, and install a 2nd bung for the wideband?

Can the AEM 30-0300 X-Series Wideband UEGO function as a narrowband just by changing the option in the software?

Found an article describing the D10 vs d14 issue on HAMotorsports' website.
"UPDATE: With all newer wideband systems that use the Bosch LSU 4.9 sensor, 0-3.73 volts reading through the stock D14 02 sensor input is more than sufficient for reading air/fuel ratio, so using the D10 ELD input is no ...

Ok i sold that ecu where the ac wasn't working and got the new one installed. Haven't tested the AC yet but was wondering about my fuel economy.

I have a AEM 30-0300 X-Series Wideband UEGO.
I hooked it up to d14 and grounded it to a26.

He can't send his ecu because his has BBG and mine doesn't. How can i get around that?

My tuner suggested I change the fuel filter because motor needs fuel for the added power. He's gonna lean the vacuum tables out and look over the tune. He also may send another p28 that's s300 ready to see if it fixes the A/C.

Heres another data log of when i was driving. I tried to use ac for a little bit as well. I plan to send this data log to my tuner and see if he can tell me why my ac wont work, why i am gettng such bad gas mileage, and why it seems to barely start although it starts every time.

How can i be sure that this ecu doesn't have the components?
And if i directly wire the compressor to the positive battery terminal it will work but does that actually solve my problem?
I have another ecu with a/c which when i hook up solves my problem, how can i socket it for hondata if it comes ...

Do i need to sell the ecu or can i get ac on it? How do I check to see if it has the components? Can you or i repair it?

ok i put the AC controls back on 5000 rpm & 36%, then i recorded this datalog. I started recording with key in accessory and then started the engine with the ac off. Then i turned on the AC and waited. Then revved it up. then waited. then turned AC off. then stopped the recording. then turned engine ...

i looked for the ecu part number but it has been removed. I bought it on eBay. The description on eBay said it was OBD1 P28 VTEC ECU computer S300 V3 cost $879.95 on Oct 2021.

The original ECU was 37820-P28-A01

the compressor clutch is not engaging. I put in the old ecu back in and the problem goes away.

Hondata re-installed, i looked at the hondata parameters and nothing is set to use the AC switch that im aware of. I checked several tabs. AC control is set to turn off at 7krpm and 100% throttle

in the ...
