i need to now if the crank sensor and the cam sensor are synchronized , this test was on a Suzuki sidekick 1998. the problem is on the live data
1)injector pulse 5ms @ 8000 rpm
2)engine load 29
3)maf sensor 4.9
4)oxygen sensor stay at 1v
5) map stays at 10
6)smoke machine test pass
7)gas pressure 35 pounds
8)exhaust has no obstruction and there is no escape
my great worries that I don't know why the engine load is at 29

Hey Carlos!

For our information, which engine does your Sidekick? Hoping it's a 1.6L, 'cause that's the only known good waveform I can find :lol:

I found this shot courtesy of the Waveform Library over at iATN. Not trying to be a salesman, but it's absolutely worth the monthly fee to be a member.



*IF* yours is a 1.6L, then it would appear that there is a timing problem. I see two crankshaft positive voltage peaks occurring within one pulse of the camshaft sensor on your capture, whereas there's only one crank peak occurring within a camshaft pulse on the known good.

Are you attempting to diagnose some specific symptoms on this Suzuki? Your O2 staying at 1V suggests there might be a rich condition, how are your fuel trims?

For me, 29% Load sounds pretty normal. There was a recent thread in which idle Load was being discussed, and I had a couple examples of known good cars with high idle Load. No known good examples from a Suzuki, unfortunately :(

Side note, I see the ETO software in your taskbar! Shame the creator got shut down by ATS...
