Default Pinging when shifting?

Hey guys, I can do pulls in each gear NP from whatever RPM with no ping, but when I shift it pings when I grab the next gear and keep going.

Experienced this while listening with the knock ears and going from 2nd to the end of 4th.

Any ideas?

Nick

Nick,

If you are hearing audible detonation you need to fix that ASAP. It's likely you have too much timing in your lower load sites around 5k and up where shifting occurs. It's also likely you need to increase your throttle pump in that area too. Check also to see if you have "decel cut" enable and if you do you may want to disable it and tune your fuel map instead or at least decrease your "dynamic enleanment."

If you have no idea what I'm talking about you need a better base map like one from Element Tuning or this stuff is going to take you forever figure out and then tune out. Sorry but you know it's only free if the unit was purchased via Element Tuning.

Good luck.
Phil

Well I'm waiting for my new Hydra 2.5 for the RS from you, hopefully it will ship tomarrow. I know exactly what your talking about, and while I'm waiting for the newer hydra I'm familiarizing myself with the software, and tuning in general.

I've got a PLX-500 w/ WB02, EGT, and knock voltage with audio output. So I plug in my headphones to listen for knock, I wasn't just driving and shifting and hearing the knock over everything else, I was tuning and going through the gears. The car doesn't ping at all when doing a pull in any gear, just doesn't like going from gear to gear.

Thanks for the tips Phil, I'll give em a try!

Nick

Oh, no, wait, stop!

Apparently I was running a map with alot more agressive timing that I thought, because I've got like 10 differant maps on my computer (the one map that keeps evolving). Anyways I got confused and loaded the one with the crazy timing changes (kinda basing my guesses off another STi map).

So low and behold I found the exact point were I was pinging, took back two degrees and added 1.5 points of fuel to the row and goll darnit she don't ping!

So I'm very happy my aggressive (for me) timing map worked. I run about 20 degrees @ 15lbs above 5k rpms! And my redline will soon be 7.5k rpms, WooT!

No doubt strong organizational skills go a long way in self-tuning something as complicated as a Hydra. Glad to hear it worked out for you.

Yes, my tuning thoughts and general advice had come from the MR2 "tuning" guide from the "unoficial hydra thread" I'd recommend it to anyone that wanted to "do it themselves" so long as they had the right equipment etc.

But if I could do it over again I'd just have gotten the autotune with it, and tune timing on a dyno after my AFRs were perfect.

I'm glad you worked it out. It sounds like you'll have no problem adapting to tuning Hydras. I just tuned a car today that had a high compression hybrid motor and it did the same thing. Locate the trouble area and removed some timing and voila

Thanks,
Phil

Is this something that can be tuned for with enginuity on the DBW cars?

I haven't seen it yet.

No this cannot be altered with Enginuity from my recollection.

Didn't think so, cause I couldn't find it.

What would happen if I changed the TPS table to ask for something greater then 0 in the 0 column above 4500 rpm?

Then it might not turn on the idle circuit and the car would stall out with a lift and clutch. I guess that wouldn't matter much as the OEM ecu already does stall out when the clutch is depressed at speed

This was always a problem mapping with the OEM ecu and any other solution really that doesn't have a tuneable deceleration fuel map. I think the only thing you can really do is take most of the timing out in that area of the map to prevent the lean ping you get on the OEM ECU during a hard lift.

Good luck.
