2 degree timing or Up Rev?

Canine · 12-11-2006, 09:03 PM

Up Rev Tuned or 2 Degree Timing Advance. Im looking to do one or the other. Any advice?

2* advance is nothing compare to the Up Rev tune. If you can get tune, don't even worry about 2* advance.

Is the Up Rev Tune done through the ECU?

Yes, they basically re-flash your ECU with a new MAP. Like myself I have 3 MAPs. Tune, stock and valet (can't rev past 3500 RPM and can't go over 70 mph

). If you can get down to Austin, do the tune.

What do you mean you cant go over 70 mph.

When I put it in "Valet" mode, you can not rev my engine past 3500 RPM and speed is limited to 70 mph. Keep the valet guy from doing donuts in my truck.

Keep in mine my stock MAP is same as before and my tuned MAP is the aggressive one. I can switch between the 3 on the fly.

BBF, how have you modded the truck to be able to shift between these modes on the fly? Do tell. That sounds interesting.

Check PM

hey San Diego titan owners! have anyone here done a 2* timing advance? where and how much? thanks!!!

ThatGuy · 12-12-2006, 03:21 PM

BBF I wanna know, I wanna know too

Also, what does it mean by "adding a chip"?

Seems like there are half a dozen choices (methods and companies) that relate to reprogramming / tuning - I would like to have at least a basic understanding of the differences.

When people are talking about a programmer coming out for the Titan, are they basically saying that they would be able to do what UpRev does?

And then there is the Cipher and Consult and maybe others - how do they relate to all this.

Sorry to have so many questions, but this whole area is totally new to me. I knew I could get a chip for my '89 SHO that would remove the rev limiter and open the butterflies earlier, but that was about it -- these seem to be way more complex. My engine knowledge is still stuck in the 70's!!! Headers, mufflers, CAI's - no problem, but this stuff is amazing.

Just today (well, yesterday), I took the post with the 2 degree advance Consult directions to my dealer, and a couple of the techs and I did the advance - they hadn't seen it before, but that was pretty easy with the Consult II. They helped for free just for the fun of it -- I think having this type of relationship with them will really pay off down the road. Well, not free -- cost me a bottle of Scotch!!!

Anyway, I'm lost in the fog, and pretty sure many of us are, and any clarification would be greatly appreciated.

i got an idea. Up Rev should just make thier tune into a piggy back for the ecu

i<3mytitan · 12-13-2006, 01:35 AM

from my limited understanding, is that while the UpRev is a reflash, it also allows the ECU to monitor any changes in condition and adjust accordingly. However, if it was a piggyback ECU, then it would overide anything the ECU was trying to correct.

BBF: i would GREATLY appreciate if you could PM me w/ exactly how you can switch between your three Maps, as I'm cuently debating whether or not to go N/A + UpRev, or go w/ the Stillen S/C

I guess if you go there, they can actually dyno tune your truck to your specifications. If you had CAI and exhaust, they can tune it to give you the max performance benefit of those mods.

In the old days, before "flash" programming became widely used, most ECU's had a small chip inside that was removable. You could replace it with a performance aftermarket chip that altered the fuel ratio, spark timing, rev limiter, etc, etc. This chip contained all of the important information on the particular engine tune from the manufacturer. Usually, each manufacturer had the same group of ECU's, but the PROM (programmable read only memory) chip was different depending on the engine and tranny options.

The best way is to tune it yourself on a dyno. However, DIY progammers for our trucks are few and far between and dyno time can get expensive. Access to a dyno is critical to reap the full benefits though. Each Titan is a little different and when you start modding, the differences become even greater. The UpRev tune on the dyno is probably best option out there for us right now. After 10-15 years when people have hacked out the flash programming source codes and found what works best for our particular engines, then that info will trickle down to the average DIY'er on enthusiast sites like this one.

In a nutshell, yes! However, don't look for a programmer with that kind of capability to come out for the DIY'er in the near future. There's too much $$$ to be made in having people pay for this service.

The Cipher and Consult II are basically diagnostic tools. They're able to check engine, tranny, BCM codes and do a small change to the timing advance, but that's about it I believe.

An '89 SHO? That was NOT exactly a simple car.lol! Didn't they have a Yamaha designed 24V 3.0L DOHC V6? I think they had lots of problems with spark plug wire fouling. I guess oil would seep down into the spark plug wells from the cam covers and get into the spark plug wire boots corroding them. That's the engine you had to take apart the whole intake manifold just to replace the spark plug wires.

That's once heck of a dealership. A bottle of Scotch would get you zip....zero....nada.... with the dealers around here. Better have at least two kilos of pure white Columbian cocaine to get anything done around here for free.
