Boondocker/OVS timing module

[smoking_powerstroke]

Has anyone had a chance to run one this year? How much did your octane requirement drop(also year of sled, how much boost, and what elevation)?? Did you see your EGTs drop in the mid range???

Right now I am running 10psi on 50/50 91/110. I am not overly worried about having to run that much race gas but I would like to see my EGTs drop while on the trail to the play areas.

Been running it for a while. I noticed the bottom end is cleaner and easier to tune and the top end cools down. I didn't notice too much in the midrange as far as temp changes. Elevation will play a role, but you should be able to run around 8-9 psi at 5000 feet plus with 91 octane.

Whats the deal with these? I thought they only pulled timing on the top. Then I was told they advance it on the bottom. Is your bottom better because you are running less octane, or does making the changes to your fueling box for the top clean up the bottom?

Is this with 2010 or 2011 stock head?

What do you estimate you could run at 2000ft?

How much do you think you would have to turn down the boost without it?

 

[RACINSTATION]

That is with the 2010 head, which is the same as 2011.

At 2000 feet I would not run over 6-7lbs on pump fuel.

Ran my 3 deg BD unit last weekend all day at 10-11 lbs with my high comp head and a 50/50 prem/AV blend. Never squeaked once. I tried the same last year w/o the module and couldnt turn up past about 6 lbs without tripping the det sensor. Did exactly as advertised. Has anyone tried out the OVS unit yet?

I bet its nice to run the 2010/11 head compared to the 09. Do you guy's notice a bit more snap?

ran mine yesterday. 1500 ft bd rg straight av gas 09 head 10-11 psi. bottom end definitely cleaned up and top end cooled off.air-fuel would drop to 10.5 under full throttle. started lowering psi lo- hi number and psi hi md,hi to bring it back ,got it to 11-11.5 full on then went home . last yr ran 8.5-9 on 91 dc out at 96.

Sounds great.
I was thinking of using rktek turbo head. But then it looks like I could pull of 6-7psi at 1000-2000ft with stock head and timing module.
Our pump gas is 98okt Ron (Norway). It compares to your 95okt i think.

My experience with the BD timing module on a 2010 M8 BD pump gas setup.

1st ride... Rode it like it has been the last 2 years (09 head, no timing module). It ran perfect as expected.

2nd ride... I put the 10 head on and the timing module. I noticed throttle response wasn't as crisp the higher I got. At about 9000 ft it started really loading up on the low end and it cleared out once I got to higher RPMs. I put the numbers down about 3 on each fuel setting. No difference. I then turned up the boost to around 9 lbs. did one big climb and then couldn't get the sled started again. Super flooded. Had to be towed out. Used about 3 gallons of gas in 8 miles.

3rd ride... put the 09 head back on and took out the timing module. Ran perfect all day.

I'm going to try a couple different timing modules while leaving the 09 head on for the next ride as it should not do this according to BD.

Vrod... not to pick on you, but you'll get much better results if you do one change at a time so that you've got a solid control & single variable. IMO, doing two changes at once makes it tougher to figure out what's going on.


Just my take.

I'm fully expecting to need to make some fueling adjustments like I did after getting the ECU flashed.

I've now talked to a few people running them who've had good results... hopefully you'll get to that point, maybe you got a lemon or something???

I'm planning on going out, doing a few pulls, then installing, so that I've got no additional variables & can make a well educated comparison (THEN I can whine about how I can't get it to work)

Just make sure to let us know how the module is working!

@backcountryislife - thanks for the constructive input bud.

 

[kraftymike]

I did the same head change and timing mod add. I had to add fuel to my PSI low maps and turn up my secondary injector cross over number to get my duty cycle back up. Took a little playing around to get it dialed again, but it was running great by the end of the day.

@backcountryislife - thanks for the constructive input bud.

Most of the time I just bring sarcasm & useless info to the mix... Gotta be helpful every now & then!!

It's always tough to restrain myself, but I hate nothing more than not knowing what cause a new issue. I also really prefer to know exactly what each mod did on it's own merit.

I have problem with my OVS timing module.
Before i used a 2,5 degree timing key to retard ignition.
Changed to stock timimg key and OVS timing module and getting scary misfires at full throttle.
Disconnected the timimg module and run stock ignition, no problem.

Push Turbo M8, pumpgas, 8 lb of boost. Seems to be around 12,5 AFR at full throttle.

Any ideas??

 

[Snopro_69]

What degree are you guys using??? PC 800 soon to have CPC 2 on it. Probably keep stock head and run 5000-7000 ft on 100LL (8-10# maybe more)....What would i gain with the different degrees of timing ?? Or if Im not going to go over 10# would I be better off and easier tuning on stock timing??

So what is the final verdict on the 2010 HO head and the timing module?

I am gonna try the BD turbo pipe out tomorrow, get it tuned up for the pipe, then I was gonna put the timing module on and see how much boost I could run on pump gas, and weight the clutch up as necessary .... then come back with the 2010 head with the hopes it'd crisp up the throttle response on the low-midrange ..... all on 91 octane gas.

Crazy thoughts or does this setup work well? Sure be nice if we had some f'ing snow to test it

 

[Snopro_69]

wanna know your results man.....hoping the HO head will help low end and the module will help us squeeze more boost outta the HO head, or else gunna get a cut head and run stock timing...putting my kit on next weekend hoping to find out wat the best way to go is

I'll post up how the pipe works, I have quite a few miles over at RE on this sled tuned the way it is now, so I'll be able to tell pretty easily if it benefits or not. If it works as advertised, the 8.4 psi it takes me at the MC lot to hit 7900 rpm should take somewhere around 7 psi to hit the same RPM.
