Sorry for not updating. I was busy with the Jeep for the few days.

The truck is currently out and I'm driving it around to break in the engine.

Here are the pending issue.


1- Engine Pinging/knocking noise.

I have Pining/knocking noise in the engine under load/acceleration. I don't have the same issue when idling or cruising. It also seems that this issue is the original cause of the engine overheating I faced before.

This needs to be investigated. Timing chain and other stuff needs to be tuned.



2- AEV Tummy Tuck.

I decided to spread the chassis. I don't believe that this will affect anything. But this was postponed until the new adjustable control arms arrive.



3- The rear Savvy Off road lights

I need to make a circuit to convert my 4 wire system to 3 wire system. So the old lights went back in for now.

Not only the love for the Jeep, my dear ... not only that!
Although there is something like a global "common sense" and basic common needs ... it gets "flavored" enough by the ones (of whatever tribe) who are "defending" their interests to cause violence and disruption.

On an individual level fortunately we all are still HUMANS! I hope our "wise" men at the top of the different "tribes" come to this wisdom too one day.

The engine is currently running on break in oil. The Golen manual recommends 10w40 which is what I'm planning to run afterwards.

The clutch is great so far! It's off-road performance haven't been tested yet.

pairing it with the B&M shifter was a great choice. The truck feels like a sport car !

I hope to get every thing done and hit the dunes by the end of this week.

It will be tough test as temperatures might exceed 48C (118F).

I don't know how you do it! Good luck though! Did you get the pinging/knocking thing sorted out?

I don't have a stroker, but I have read on this forum and my club's forum that adjusting the crank position sensor will help with the problems you have. You can get one that is adjustable or slot the holes in the one you have.

Also, an adjustable MAP sensor was mentioned.

Thanks for the info!

oalali, man ... didn't you do a paint job to your intake manifold as well?
If the sealing surfaces (towards block and towards throttle body) e.g. got painted too you might experience vacuum leak issues which can be another reason for pinging!!! I would strongly recommend disassembling the intake and TB stuff and eventually cleaning the surfaces from the paint with thinner! (no sanding or other invasive methods!!!)

Thanks!

The truck is at the Dyno today and I believe that they will be able to diagnose the issue.

This may sound strange, but I'm suspecting that the engine is actually running rich! This can be either caused by too much fuel or too little air.

The intake leak might be a possibility. But they haven't painted any contact surface. Also, All surfaces where cleaned before the installation. Anyway, I will get them to inspect it for any leaks.

I'm also installing a fuel regulator and fuel/ignition Chip to deal with this. I hope to get some positive results today. Wish me luck !

Sorry for not updating, here is what happened so far:

After few dyno inspections runs, we discovered that the engine is running rich while idle and lean while on load.

The tuner tried to fix this by installing AEM's F/IC8 controller. After a 3 degree retard and fuel table adjustment, the results became as following:

1- On idle, the engine is running way too rich.
2- On load, the fuel is better but is still a bit lean.
3- Knock was eliminated until engine reaches above average temperature.
4- Fuel consumption is very high.

We stopped right there. We can't retard the timing, or increase the fuel anymore as the engine had some hard time starting. Also the fuel consumption was very bad.


To be continued ..
