Nistune Forums

Hi!

I have got a S14a with the SR20DET engine, european model. What I now have noticed since I changed the MAF and injectors is that the engine is flooded during start. I have run the MAF and injector resize wizard in Nistune. I think I have found the problem but cannot understand why it is like this. The problem seems to be that the temperature that the maps uses is always -40 degrees, even if the engine is hot. The temperature gauge in the instrument cluster works ok, Nistune reports normal Temp in the "Display consult gauges" window but still the selected value in for example "Engine Crank Offset" is the one under -40.

What temperature exactly is this which is used and how can I diagnose it? I have no DTCs.

Thankful for advice!

map trace doesnt function on that table. it has been fixed in the current code but not available for download yet

half the crank offset value table and that should sort the flooding at start issue

OK, noticed afterwards that maptrace on other temperature dependant maps worked.

Should I half the values in all crank maps or just the Engine Crank Offset map?

Engine crank offset seems to make the difference

See the post here 3/4 in the thread that I made
