Just wandering if my car will work without a chip in it atall. Obviously it will not run very well but can I get from a to b without damaging something?

Erm, NO! The chip contains ALL the fueling and timing data and if it aint there the car won't run.

Why would you want to do that anyway?

because after fitting larger injectors myself now might need to get somewhere to get chip fitted as it doesn't run very well with old chip.

I'm not surprised ! I can socket it for you if you have a suitable chip. If not and you have a manual box then you could use one of Devin's maps that are downloadable from his site.

is already socket ta, but might go for custom mapped from se nissan.
