I sent up a chip which will probably run lean in your car just send back the one you like the least... :-)
vince tings rich condition turned out to be a bad AMM & did not run as well with the leaner chip I sent him although his wideband showed reasonable AFs with it it may be that his widebend needs calibration this happens from time to time
frank stromqvist wasent super impressed with my LM1 either he said it wasent bad but not that good either....\
on the ECU there is a cold start & warm up map which runs what ever spot you are on the main PT map richer grounding the o2 wire will only make this worse
the ECU does not need to ignore the o2 signal once the 02 warmes up enough to get the voltage up it starts corecting (atempting closed loop)
modern engine management goes into closed loop within a minute or 2 with the heated o2 sensors & grounded signals (more true)
Im glad its running better :-)
take care
JAK
