3rd gen timing the old fashioned way...

[SRadke]

Testing sounds interesting... you thnik you can sway me away from my TST box?

There is no way that we will be able to re-create the massive amounts of low end torque or the low end fuleing of the TST. We will be able to provide good power that is useable and drivable. We should not be killing turbos and such. So I doubt we will take away the TST guys, but it will be a good option for those that want mileage and some horsepower without going completely crazy!

That is exactly what I am wanting. Where are yall located in Texas. I work in the Greenville area.

 

[qzilla]

We are in Ft Worth. I see you have a 04. 5, we will definately want 600 beta testers. I am not real sure if we have that problem completely fixed or not yet.



The 600's are frustrating because you can have 100 trucks work perfect and 10 have problems?? Make it a nightmare.





Make sure and contact us when we ask for beta testers in a couple of weeks.

It may be bennificial to test one on a 250 hp SO such as mine as well. The program TST uses for the 305/555's didn't work right for me so I had to go back, get it on their dyno and modify the program. Apparently it is an anomoly not found in the Cali 230's.

Well I can speak for a couple of 600s.



I have a 555, buddy has 600 and dad has 600.



Count me in on the beta testing. I'm in Michigan. Also have a buddy into fuel injection systems.

Isn't there a blank spot on the crank position tone wheel ? ( '04 305/355 ) would that set a code if the initial positions on the cam and crank transmitters did not line up every other revolution?????

I crawled under it tonight and saw that Peter is right, that the crank sensor does indeed have a "home" position. Both sensors would have to move. Oh well, at this time I will be returning to reality (at least temporarily).



Qzilla, got room for one more beta tester?

I would love to test out a timing only box. Woo hoooo! A 3 box stack! Oo.

 

[krabman]

I would be able to offer immpressions on how the box works on an injectored truck that is driven daily and tows. Oh, and its grey, your certainly gonna want to know how it reacts to being installed in a grey truck.

 

[jstrong]

I work in Downtown Ft Worth and would be willing to do Beta testing and even think about leaving it there if it would help.

 

[qzilla]

As soon as we get everything ready to go I will contact all of you guys.



It should be in the next couple of weeks.



Also just for safe keeping if you can pm me with you email or however you want to be contacted it would be much easier to keep up with all of you!

Make that 2 solutions

Just guessing here and this is based on gas knowledge but...

The crank sensor should be in control of timing while the cam sensor simply gives the ECM the info needed for the firing order sequence.



The cam sensor should have only one point that says its at #1 cylinder and then the ECM injects off through the engines firing order. While that sequence is going the actual injection start time would need to be controlled by the crank sensor as it is telling the ECM where the piston is.



Now if the cam sensor has 6 slots vs 1 then this thinking could be wrong.

 

[OT-OF-HERE!!]

Wondering?

Actually, if it works the way I think it does, you shouldn't have to touch the crank sensor, only move the cam sensor by 6°. I'm heading out for the 4th, but if I get some time next week, I'll try and R&R the cam sensor to explore the possibilities. This is not something where you can dial in any timing change you want. It would only be in 6° fixed increments because the teeth on the crank gear are 6° apart.



The way I think this works, the crank sensor is used for engine speed sensing and has no "home" or TDC measurement capacity. The cam sensor has the ability to find "home" or TDC. It has a magnet on the back of the cam gear that must pass past the sensor to generate that signal. This is why the electronic controlled engines seem to crank longer, that magnet MUST pass the sensor at TDC. According to what I've read in the service manual, this is ONLY looked at during start up, then the whole operation runs off of the incremental crank sensor signal.



I'd really like others to read the pertinent sections of the service manual to see if they agree with my assumptions of how this works or point out where I missed something. BTW, I don't know if 6° is too much. From what I know of gas engines, it's probably helpful. Someone else can weigh in on that.



Guys, I'm just exploring options here since the box solutions haven't been materializing.

Could the crank harmonic balancer be keyed with an offset key and get say 2 or 3 degrees? Works on gassers.

 

[R.M.THOMPSON]

OUT-OF HERE,

How about a custom balancer , keyway filled and moved the amount to suit !!!!! Mayby you hit the nail on the head . Just have to have some service to do an exchange for core credit.
