Good Tec3 map for a 2000 RS Vishnu kit

david2z4 · 10-21-2002, 09:45 PM

Anyone have a TEC3 map that is tuned well on a 2000 RS with the following.

Vishnu RS turbo kit
550 injectors.

If you do maybe you could email me a copy of them.

Thanks

Dave

want to add that I had it tuned pretty good, then when I put it the 12 lb flywheel and new up and down pipe on, now it runs way different.

It is really rich and I can't get it to run good with the normal adjustments that I have made in the past.

Pulled the spark plugs and they are clean. Wonder what I am doing wrong.

When does it run differently? Cold start? Warm up? Steady state cruise? In boost?

Can you not get it to idle now, or does the car surge?

I get lean lope at idle when warm but it is not lean.

It starts harder cold and warm

about the only time it seems to run good is under boost.

gas mileage is way down.

I think I blew another O2 sensor to due to being to rich. the voltage just started oscillating from .2 to 4.5. but it ran bad before that went out again. May have to buy them by bulk the rate I go through them.

I think my o2 went too. It reads 0-5 mostly. It is supposed to be reading anywhere between 80-95.

What about your battery Dave? Now that I think about it... it makes sense. I remember you telling me that the TEC3 is voltage dependant. So at idle, it could idle funny because you aren't getting juice to the battery because the engine isn't spinning the alternator fast enough. At boost your car is spinning the alternator fast so it compesates for the fact that the battery isn't holding voltage.

What do you think?
