setup:
OEM sensor on throttle-body.
GM 3bar on firewall
wire harness is stock but with 3bar sensor spliced into OEM wiring.
Checked voltage coming out of 3bar using a piece of tube to blow into, voltage changed fine, checked voltage at ecu connector, voltage comes through just fine.
The problem is hondata just reads -29psi
plugged the OEM sensor in, same reading, re-uploaded a new maw with just injector sizes, then on the sensor info pane MAP just says 0psi! on either sensor. I had selected the correct types for each sensor.
Im guessing this is a ECU issue? but the ecu was socketed by Hondata! throgh Jeff @ importbuilders.
any advice tips???
can I sent it back for testing? or any better advice?
