I´m not a "Nissan man" but i HAVE owned a 1991 primera GT, and i belive that car had the SR20 engine ?, was a 2 litre MPI 140hp engine.

Purky engine

And all that with the same strict emissions rules you have "over there" (we have the same ones since 1989).

Ok I will check it out - is there any new settings that I need to use to take advantage of the high res injection? Like, is it a feature that goes un noticed except in car performance or do I have to set it up or anything? Also, does it make that much of a difference?

It´s just "there" when ...

Check in to the msns-e 1 /development area on the forum and you´ll find the thread.

Last version is in the first post. But it´s not considered "finished" yet though.

It´s based mainly on the 029 code though so i should not worry to much. The only function taken out of the extra code to make ...

If you´re pending around 2ms pulswidth at idle you should try the hi-res code :!: , my machine was doing a bit like yours but when i switched to hi-res 08 it disappeared.

Also.... setting the bins to the same value doesn´t mean that the afr:s are the same at slightly different kpa:s around idle ...

I will be very interested in MS setups for a 4-cyl using a single TBI700.

Mine is like that.... single TBI700 injector.

One thing i´ve noticed is that they´re REALLY low impedance, approx 1.6 to 2.1 ohms on different types.

And they need very little current to work.

I have a 6.8ohm series ...

Ah , sorry.... english isn´t my native language

It came from a Citroen/Peugeot XU9M DDZ monopoint(TBI) 1.9liter 110hp engine.

Sits in som peugeot 309/405 and some citroen BX.
