ECU Timming issues

[lazii boi87]

I got a chiped p28 obd1 ECU my car is obd2 (97Civic CX B18c1 swap) and when i run my chiped ECu my car runs way better accept the fact that my car idle weird an low like under 1rpm and it like hezates like stuttering it even messis me up when Im start on first gear and it does the same thing when I'm trying to drive slow.if its accelerating it doesnt act up but when i put my obd2 ecu my car doesnt act up at all i rember the guy who chipped my ecu told me he advanced the timing a lil and i told this to the guy who put my motor in and he said just push the dizzy a lil towards the firewall and this should fix the problem. do yall think somthin wrong with the ecu or advancing the timing wasnt a good idea?????

Is the car throwing any codes?

Also what OBD2 ecu are you using?

Did you properly convert the car over to OBD1... meaning did you convert the 3 wire IACV to the 2 wire IACV properly?

is that done somewhere else besides the conversion harness
