I made some headway on the motor last night.
I pulled the fuel filters apart and did an inspection and cleaned them. I finally found a use for my can of Coleman lantern fluid! It worked well
for a cleaning solvent.
The filters were not as bad as I suspected. Sure they had some sand and a blade of grass in the 100 micron pre filter...but given the enviroment that the fuel cell is exposed to, I felt they were actually fairly clean.
There were signs of that foam insert breaking down also...but Not so much that I should be concerned.
The filters are doing their job.
Here are a few pics of them apart and what I found.
First pics are of the POST 6 micron filter up front:
The next few pics are of the rear 100 micron PRE filter :
In that last pic I highlighted the fuel cell foam particles.
So after reinstalling the cleaned filters I thought I would start with a fresh tune for the motor..instead of sorting out the mess we had with Saturdays
tune.
I used the dyno tune for a base, and altered it from there.. I seen where the tuner had the base fuel set at 115% when engine reached 160* and up..
This explains the extra 15% of fuel spitting out the collector I was seeing.
Once I felt OK with the tune , I uploaded it to the ECU and fired up the engine... I'll be damned if that thing instantly started and purred like a kitten.
No stumbling or high reving....just a smooth idle.
After it got up to temp , I turned on the learn and logging...I slowly took it up to around 3500 rpm's and back down, then stopped the logging.
I shut off engine and began to look at the graphs and charts...
Now I am still learning about tuning ,so I watched a few videos on the sniper tuning and have a long way to go , but form what I have learned so far ...
all is looking good as far as the base goes..
I will have to recheck timing and (IAC) and the (TPS) positioning tonight to make sure they are correct.
This is something I have learned may have been a problem with Saturdays tune..
Like I said ...I am slowly learning.
Thats my update for the day guys!
