LT5 hesitation... - ZR-1 Net Registry Forums

... which Marc says ALL LT5's have...

I still have a small amount of water in my tank - hardly noticeable, and it will all be out after a few more drives.

But something came to me here this morning, related to the residual water. When backing uphill, up my driveway, she struggles. Warmed up, it's not noticeable even.

But backing uphill cold, RPM's are probably right about 1.6% throttle. Which is where DataMaster showed the hesitation, and LOPE - from 1.6 - 2.4% TO. LIKE a vacuum leak, if throttle linkage is HELD at that throttle position... Like the pulsewidth / gas isn't sufficiently calibrated @ that throttle position...

Now I have a little water still mixed in. Even LESS gas, exacerbating the problem.

The water isn't the issue, because it will shortly be spent.

The issue is the pulsewidth calibration at that TO %.

Any thoughts here on increasing the pulsewidth at the 1.6 - 2.4% TO position???
