SSR New Release Info and Results Thread...

Maybe this way of looking at these numbers will work with EFI style tuning better, I dunno. Thinking out loud here.

Has anyone correlated smarty's timing numbers to duration numbers?

Like. HLT of 20 will never ever be enough timing to allow a HLD of 30 to burn properly? Or something to that nature.

tho to hawaiiankine point, less timing and more duration for smaller injectors, one could assume from that, that the higher duration numbers would behind the scenes push the timing numbers higher to accommodate for that duration.

I certainly figured that was the case, but I've never played with smaller injectors with the ssr. :)

So back to my original correlation thought... Could one draw up a table of timing vs duration values?
 
So in theory if you took 2 same setups and one had smaller injectors than the other the size of the injector wouldn't make a difference on timing or duration numbers? I haven't played with different size injectors but from what I've read on here with different peoples values and what I've experienced it seemed like different injectors did have an impact on what duration and timing values you use. Could be wrong.. it was just an observation.

Ok...
I will bite on this one and ask a question after seeing what I seen in a recent dyno session....

Are you saying that injector size has nothing to do with what duration and timing the SSR will take to utilize the fuel they make available?

The SSR numbers for duration and timing on my truck were significantly different between my 35LPM and my 65LPM so I am not following what your telling us?
 
Temps have dropped to the mid 30's so I'm out testing the new sensors.

I can't get 1.6 dialed in worth of crap. It's an OBVIOUS seat of the pants loss in power. To dial out the rattles. pressure or timing are a lot more defined and a change of the tune is a notable change in how things drive and sound. With that said, a loss of 10psi in OD WOT is something you can tell on the road vs dyno :) I've always felt 1.6 was a dog on the low end and seem to fall flat on the big end of rpm range.

I'm sure I can possibly find that 10psi of boost with tightening up the gate a little. but the drive is 60 in 1-3rd so I think the gate is for the most part fine.

Do get me wrong I can bump the numbers up and get decent performance with 1.6, but pressure and/or timing rattle needs to come into play to get the truck to run stronger.

I'm dropping back to 1.5 for comparison after lunch here. hopefully this entire sensor replacement wasn't a placebo affect or something, it was much warmer out when I was playing with 1.5 and new sensors (50 degrees). stay tuned.

geez I got some work to do, driving home today and got stuck goin about 55 mph. light to no throttle and the rattle sounded like it was trying to get out of the motor. I did well on fuel tho, 440 miles round trip, plus driving around the gamelands for three days and I got an 1/8th left.

Not to get off topic but besides the fuel mileage, any luck in the woods?
 
I never said anything about duration...

Injector size by itself really has nothing to do with timing...more the design of the injector.

A large honed injector will not like a lot of timing...a smaller honed injector will tolerate a little.

Duration is totally independant of the two.


People need to heed to Marcos original tuning instructions....its really that simple. Shooting around with number after number does not work. Start at stock timing...adjust duration till you have smoke you can't clear...back off a little. Riase pressure till your happy with the peak....then add timing till the power no longer increases...then back off the timing a little. Less timing in the LL will help spool chargers quicker.

You have to have a track, dyno, or a really really good butt dyno to do the timing.
 
Well. the rattling is still there, just not as bad. There seems to be some sort of improvement. :( 1.5 > 1.6 for me. seem as if it's more of a too much fuel noise then timing. tough to tell some times.. lowering the duration helps more then timing. BUT. if I lower the LLD to say 8 from 12, the low end power drops.. heck, 40psi is about all the boost it'll make at 2200-2300rpm in OD. heh.

Next up. FCA's and pressure sensors.
 
You would make more power on stock stick with your charger and wouldnt be trying to get rid of a rattle that is not going to go away without compounds or smaller sticks

You seriously think there's enough fuel in stock injectors for 750-775whp (peak). If you have a set and some cash for dyno runs, by all means send that stuff up here and i'll split the dyno time with ya. You just tell me the numbers to run for stock injectors and i'll make 3 pulls on the same dyno a day apart. DynoDnamics up here, the guy runs my truck consistently but the numbers are low vs a dynojet. If you can make stock sticks faster/more power then my 100's over, i'll buy them.

There was improvement over the sensor change. I'm fairly confident in that everything is snappier.

The truck will be parked mostly here very soon once the snow starts falling. When it was in the mid 50s out it was nearly perfect in all situations. That was just 20 degrees of temperature ago. It runs very well right now once you get past that first few psi. Maybe it could use a few notches lower on the LLT.

Ver 1.5
TM 1
RPM high
LLT 22
LLD 12
LLR 1
HLT 36
HLD 16
HLR 8

heh. next time I'm in town, i"ll take you up on that offer.

Do you recall Marco him self couldn't get more than 711peak hp with 90's and twins? What makes you think stock injectors will? :poke: :stab:

I've thought about taping wires and mucking with the coolant sensor for starters as of recent. There are a few characteristics of a "warming up motor" I'm curious about once it's really warmed up, but the ECU thinks it isn't.....
 
Sigh, I wish at this point that Marco and Bob would tour the US a bit, stopping in at several locations, call it a customer support tour. Stoipping in and chatting with folks, see what wishes they have for the tuner, seeing what if any help can be given to tune trucks. I would drive 250 miles to meet and discuss things, and let Marco try his hand at taming my rattle. Hearing ideas from customers on stuff like tuning options, simple stuff like selecting at what rpm the pre injection shot is turned off, adding features like trans control, something like a tunable lockup option something like the co pilot does but right there in the tuner. Options on selecting when the post event shuts off...... Maybe some of this is coming in the UDC update, but who knows. I do know I am glad I have a second vehicle to drive so I have less chance at damaging anything from the rattle I have. I know Marco is from Italy, Bob is over on the west coast, but planing a US tour for next spring would allow for the best coverage of the us in an efficient manor. We could set up a poll asking folks where they would like to have an event at, and let the numbers speak for themselves, and allow Marco to decide which ones to go to.
