OBD1 S300 help with wideband and tune

[simmo490]

Hi Guys

I have been asked to sort a mini out with a Vtech running an OBD1 and AEM LC-2 Wideband.

The spec is as follows

ITB`s
TPS (0-100%)
no MAP sensor
AEM LC-2 Wideband
440c Injectors

After lots of reading i see i can run the Wideband sensor input (0-5v) in the o2 sensor input D14 and change it in the Smanager as required. OR i can run the Wideband input in to D10 (ELD) and change this in Smanager.

The car has a base map and was having 50-100% load problems so i have been having a fiddle with swapping the wideband input between D10 and D14. i think i have re calibrated the wideband when hot so not running too good now (worse than before) will wait untill the car cools down before i recalibrate.

I have a feeling we need to be running a MAP sensor for when not using wideband. I have uploaded our base map.

My questions are

a) how does the basemap look?
b) do we need to be running a MAP
c) with the attached map where should we be running wideband , d10 or d14? and i take it no narrow band needed?

Looking thorugh the forum lots of helpfull tips. This is a steep learning curve for me on the honda ecu so any information is great.

Thanks

Dave

What is the reason for not using a MAP sensor

[simmo490]

Just never came with the setup. Previous guy said it never ran one.

You really need to have a MAP sensor and then use Alpha-N to properly tune it.,

Sorry. Alpha n ??

We are getting a map sensor for it. But as it stands with the setup how does the base map look. Thanks
