Default UTEC Gurus HELP, Transition knock

I am having problems with knock when I shift and its happening right when i get back on the throttle from shifting gears. I am shifting somewhat aggressive but nothing crazy like im racing someone. Anyways, my map is pretty solid, if i pull my car from 2000 rpm to redline in any gear, my car does not knock and has a A/F of 11.0 at around 3000 to redline.

Our theory (my tuner and I)
When i let off the gas to shift gears, at that instant, my load site goes to 0. When i quickly get back on it (100% throttle) after i shift my load jumps from 0 to 40% in a split second. We think that because the utec doesnt process or map quick enough, it isnt able to provide a smooth transition and my car is starved of gas and i encounter knock.

I also encounter this knock when im in 2nd gear and im at around 4000 rpm, with no load on the car (20% throttle). If i was to then SMASH on the pedal its very similar to the shift knock, my load jumps from 0 to 40% and knocks at that point. (same happens in every gear)

I feel like if we had more load sites, better resolution and faster mapping/processing, we could eliminate this. We tried looking at the parameters and really didnt find anythin that could help us. My utec maps from -1 to 12psi, and my load goes up to 80% at full boost.

We've been pulling timing from the rpm/load sites that i encounter this knock but we are at the point where my timing is getting pretty conservative. Should i keep pulling? any suggestions would help! thanks in advance

Brian,

I have tuned many UTEC's that have been setup incorrectly elsewhere and have a switchover problem. The UTEC shouldn't hesitate or have an unsmooth transistion between the "0" and other columns. If it does watch your air-fuel ratios and timing closely. When this happens do you notice the air-fuel ratios go from richer to leaner or vice versa? Do you notice a huge swing in timing?

If so, make sure you factory injector trim is as close to zero/100 as possible. Then smooth out the air-fuel ratio differential and you should have an unoticable transition. If you notice a huge swing in timing smooth out this transition.

Hope this helps,

BrokeZ,

Please post a datalog of the knock event using the number data logger. Try to get at least 3 seperate occasions. This way I can let you know what needs to be done with your map to fix the problem.

Thanks,

Jermaine~

A/F seems to be good, and my timing was at 9 just before i knocked. This kind of stuff just confuses me.

Also, I changed around my knock settings before i logged those. I turned the sensitivity down to these settings, does it seem too low?

Knock Threshold idle to 2000 RPM (0 to 125) : 85
Knock Threshold 2000 to 3000 RPM (0 to 125) : 70
Knock Threshold 3000 to 4000 RPM (0 to 125) : 70
Knock Threshold 4000 to 5000 RPM (0 to 125) : 70
Knock Threshold 5000 to 6000 RPM (0 to 125) : 60
Knock Threshold 6000 to 7000 RPM (0 to 125) : 55
Knock Threshold 7000 to 8000 RPM (0 to 125) : 55
Knock Threshold 8000+ RPM (0 to 125) : 50
Knock Count Threshold (1 to 100) : 2
Knock Retard Step (degrees) (0 to 10) : 1
Knock Maximum Retard (degrees) (0 to 30) : 10
Knock Retard Duration (crank cycles) (0 to 1000) : 50
For Future Use : 0
Timing Maps Knock Retard Step (degrees) (0 to 1) : 0.5
Timing Maps Knock Maximum Retard (degrees) (0 to 5) : 5
Timing Maps Knock Window Time (seconds) (1 to 20) : 5

Also, I advanced timing on my whole map by 1degree after i lowered the sensitivity.

Ok, to start. If you knock and in a portion of the map this has (ECU) for a timing value, the timing will not be retarded.

All of your datalogs have me wondering what is your Open Loop Map Threshold setting in the Open Loop Fuelling Parameter. Humor me by changing it to 0 psi. This will allow you to crossover alot sooner.

Code:
4714 +7.0 4.9 102 70 00 21.23 +13.0 83.0 +9.2 -2.0 4.6 11.23
4852 +7.0 5.0 102 70 02 21.37 +12.1 85.6 +2.7 -3.0 4.6 11.39
4887 +7.2 5.0 102 70 00 21.52 +12.8 87.6 +2.7 -3.0 4.6 11.58
5005 +7.2 5.0 102 70 00 21.69 +14.9 91.6 +8.7 -3.0 4.6 11.62
Honestly this portion of the map looks like you are running too much timing for the current AFR. The factory ecu is seeing the detonation as well.

My open loop map threshold was already at 0psi.

I will retard timing by 1degree in that area and see what happens.

Also, i noticed since ive turned down the sensitivity on the knock threshold i have seen a much less occurence of the shift knock.

Jermaine,
Thanks for the help, any further advice is also appreciated.

Brian - has this been happening for a while? Have you had a chance to re-fill your gas tank to eliminate the possibility of bad gas? It is unusual to have to run lower than 10 deg. timing with the UTEC at your boost level assuming you are running 93-octane gas.

If retarding the timing 1 deg. in that area does not help, try taking 3 degrees out to see if it goes away. I would suspect there is another problem if the knock does not goes away at this point. If you can do datalog from 1,500rpm to your maximum rpm for us to look at.

I also like to set the "Timing Maps Knock Retard Step" to "0" (zero) when I am tuning, and put back to 0.5 deg. when tuning is finished.

ps - what size injectors are you running, I noticed you are over 90% duty cycle at only 7psi/5000rpm?

Hope this helps,

Mike, I am running 92 octane here in WA, but i hear its just as bad as the 91 in cali. I have access to 94 in my area which I will probably consider using now. Phil from element tuning (i believe you know him) was in the area and tuned my car and even told me that because of the quality of gas, cars from the eastcoast are usually able to run a little more aggressive timing (1-2 degrees) based on his experience.

I also like to set the "Timing Maps Knock Retard Step" to "0" (zero) when I am tuning, and put back to 0.5 deg. when tuning is finished.
Thats probably a good idea.. ive been turning off my car and restarting after every time i log and find knock..lol.. dont ask me why.

ps - what size injectors are you running, I noticed you are over 90% duty cycle at only 7psi/5000rpm?
Im running the PE 380CC injectors. However i have a question regarding how to set it up on the utec. I have it set at 380 on both the stock injector value and the modified injector value. Maybe this is why its showing above 90% duty cycle at only around 7psi. Should i input the stock injector value? (isnt it 290 or so?)

Anyways, i will get a log of 1500 to redline tomorrow when i get a chance.. thanks for taking a look and helping me out.

BTW, Mike, I originally bought the base map from you for the PE kit, I dont know if you remember.

Broke,

Post your paramter file. It still looks as though you are crossing over very late. With 0 in that parameters. YOu are also jumping immediately to the maybe 0 to 30 colums cutting your mapping resolution which is probably why you are knocking as well. I think your minimum psi for mapping needs to be adjusted as well.

Thanks,

Jermaine~

Broke,

The 380cc injectors are very small for any twin turbo kit, and are usually around 90-100% duty cylce between 375 and 400rwhp.

Try the 94-octane gas to see if that helps.

I think Jermaine and I are getting at the same thing. I am courious to see the 1,500rpm to redline log so I can see how your car transitions from ECU to the map sensor.

alright, here is the 1500 to redline log.. a couple things are obvious to me that i need to change..

1) 2500-4500, i need to add a bit of fuel @ 70% load to richen it up a little bit.

2) my injectors, i have no control over them at 5500 rpm, I might pull another degree of timing there till i get pe 510 injectors.

A good thing though, no knock... Honestly the biggest difference was turning down the knock sensitivity a little bit. What do you guys think.

It looks like you can improve your setup some by chaning your switchover point. It looks like you are into the 30% columns before it kicks out of "ECU". Try lowering your switchover point to see if this helps. I see that you are at the Zero load point at -0.1 and at the 30 load point at only 0.6! I like to start map minimum value to around 1psi -- if you change this it will slighlty offset your entire map so you'll need to rework all the fuel & timing values a little.

I normally setup the knock threshold from low rpms to 3000-4000rpm a good ten more, so I definatly wouldn't lower these any further. Make sure you do not hear any detonation.

Let me know how this works!

Hope this helps,

have you tried changing the value of the "open to closed loop delay?"

in the manaul, it says that this delay is particularly useful for preventing "shift knock."

try changing the value to 1 or 2.
