My 90 NA is a put together from 3 cars.. I have Cold Start Issues.. It floods BAD when cold.. warm or restarts are fine.. Also it would flood just off idle when below 1K rpm when taking off from a Lite or stop sign.. I just went ahead and changed the PROM Tables for Cold Start Enrichment and Throttle Enrichment.. It's not perfect, but much better now.. There is only so many times I was going to swap parts between my other cars, and end up with the same results.. So I was able to tune around it.. I used the Moates battery ROM and tuner pro software, until I got the ROM as close as I thought was nessasary, then Burned a ROM and inserted it.. that's why I did this a few years ago [ http://www.twinturbo.net/nissan/300zx/forums/technical/view/1147286/Chipping-the-ECU.html ] Cj
