Yeah a lot of the tutorials had incorrect information out there

Glad to hear! this video hasn't gotten a ton of views, hopefully it will catch on eventually ;)

@@CanyonTuned It seems to only pop at 3-4k RPM, any higher or any lower and it doesn't pop at all, I followed all the steps in the video, any tips? Tysm! (I have a vid of the pops posted as my most recent video)

Yeah I've noticed that too actually, you may want to add in some additional fuel (just a very small amount) or try to take some more timing out of it

It also just hit me yours is a gen iv so there could be other decel timing tables that are taking over. Try to log timing and see if its actually pulling it correctly

hell yea

Good to hear! A lot of people are changing 5+ tables and making things more complicated then they have to be. This method is easy

@@CanyonTuned just got back from a drive. -5 didn't do much. Went -10 and it's occasional in only 3rd gear and above. I did set the park and drive tables the same and also the minimum spark retard table. I could throw fuel at it but I just wanted to see how this worked. Stock everything with bad cats haha

@@yz250ftony Auto i'm assuming? I know others got it to work with auto cars with some extra fiddling, I just don't have an auto car to mess around with to figure out how to make it happen all the time

@@CanyonTuned z06, 6 speed

@@CanyonTuned Update: after a month, my throttle started sticking open at the rpm range i modified. I went back to original settings and fixed it.

You must have something else going on, there's no reason throttle hang would happen from this. I have the same car 04 z06

Log your TPS and report back, i'm curious what the numbers are when this is happening

@@CanyonTuned I haven't logged before. Is that an upgraded feature? After a pull, the throttle was hanging open in the RPM range I had altered and just sitting there. Shutting off the ignition and restarting brought the idle back down to normal. If I go back, I'll log it but I don't want to risk damaging the o2 sensors with the extra heat.

Logging is built into hptuners, also I would check that your throttle body is working properly mechanically and that you don't have vaccum leaks. I've done this on a few cars now and haven't run into this

@@CanyonTuned I'll look into logging. No leaks, I had the intake off a couple months ago. Just found a lot of oil sitting in it. Added a check valve and a catch can to the pcv line. Idle is normal. Everything is clean and in good shape.

With most ECUs just edit the main timing table. Change your low load/high rpm cells to negative timing. Then in your fuel table add a little bit in the same load/rpm cells. You might have deceleration settings that turn off fuel when letting off the throttle, change those to add a little fuel on deceleration. Fuel + retarded timing = pops/bangs

You should only need to play with the negative(-) timing to increase the pop effect, just keep saving versions (save as) as you figure things out

Canyon Tuned and how about the chop

Also, what kind of kPa did you pull on decel? My car never seems to get below 34 on decel. Problematic as this is within my cruising zone.

The stock ecu is setup to always hit your target afr based on o2 feedback and fuel trims. You'll really only gain fuel economy by adding some timing in cruising conditions to make the engine more efficient

Try harder. It's worked for literally hundreds of people at this point. You probably have an auto and need to mess with some additional tables

Car has longtubes and a y-pipe

I believe for automatic cars there's a 2nd table you need to modify. It should be in the same section as the table in the video

@@CanyonTuned under which section?

did you modified idle spark advance "in park" and "in drive" as well? both tables are only for throttle closed conditions. the High octane and low octane tables are for conditions where throttle is open in any ways

Technically it would be less efficient since you're burning fuel in the exhaust instead of the engine

@@CanyonTuned But if you're not adding any fuel to the tables then the engine can't benefit from it? I'm thinking environment wise, if you retard timing so that the unburnt fuel ignites in your exhaust, wouldn't that benefit the environment instead of letting the unburnt fuel go to the atmosphere?

@@z3r3pmoto It would be worse emissions wise, retarding timing and burning fuel in the exhaust will just overheat the cats and make them work outside of their efficiency zone. Not to mention you will blow the cells out of your cats after a while as well. But yes, you are not consuming any additional fuel (unless you modify your fuel maps as stated in the video).

Take as much timing out as possible some ecus you can do like -25, turn off decel fuel cut, and add a bunch of fuel in the decel area of your ve table

Depends on how aggressive you have it set and the frequency but even oem cars have burbles now

@@CanyonTuned Thanks for the response. I wasn't looking for anything crazy so I set both idle tables to 5 degrees.

Hp Tuners

As low as -20 degrees. Can’t edit on mobile.

Log the car and observe what idle is

So I did do this, and from a standstill idle is about 5.5g/sec I think. Can’t remember, all I remember is all the values for the MAF calibration were above that to begin with. What am I missing?

7.5g/s. Still a lower reading than the stock MAF settings. Don’t know how it should work.

Tuning cars requires attention to detail. By default the logger and editor will be in two different units of measurement so you're not even looking at the same scale like for like. Secondly, unless you disable DEFCO, decel fuel cut. None of those maf air flow changes are even going to matter.

Help with what specifically? I think we're talking about two different things. I work with GM LS tuning not Honda/Acura LS stuff

You just have to retard the timing more, also add a bit of fuel in your VE/MAF tables on decel

Process and tables are completely different for gen IV

The LSA already has it built in from my experience. You should be able to get darn close to their stock tune as a jumpoff.

@@scottleggejr Has what from stock? I have an LS3, but I was just wondering about the particular settings. I still haven’t messed with my HP Tuners in that DSCO (can’t remember the name) section or whatever. I’m shooting flames if I rev bomb above 5-6k, and backfiring occasionally above 3-3.5k on upshifts and revving. I’m currently running offroad/catless connection pipes to my long tube headers, and non-resonated mid pipes, so I’m not surprised. Lol I do have mufflers, but they’re probably getting burnt out from me doing that.

@@isnowyazn You should be able to find an LSA hpt file online and compare the tables. The LSA has a significant crack/pop on decel when you engine brake. Specifically, you would NOT want enrichment on a boost blowoff event.

@@scottleggejrWhat exactly should I be changing and not changing though, as that’s a completely different setup…. The only tuning I’ve messed with, is through a basic (1-hr long) HP Tuners “tutorial” by some dude on KZfaq, where he basically just smoothens out the enrichment levels and turns on and off some management stuff (CAGS, etc).

Nope! That's the best part. The way I have it configured it only changes the idle advance at higher rpms. I noticed no throttle response issues either

@@CanyonTuned Thank you!

My C5 is an auto, with a decent sized cam. It chops hard in park neutral but as soon as I turn the AC on it smoothes out quite a bit. I know its the added air when the compressor kicks on but I can't find the table to lower it on the gen 3. Any help would be appreciated brother. Im still trying to learn tuning so kind of new at this.

Oh shoot, you know I was just looking at those tables the other day! I think there's specific tables for AC fuel/spark. I'll have to see where that is again. Usually cars will have higher idle targets when the ac is on. Aka less cam chop

@@CanyonTuned thank you so much just let me know when you find it maybe you can guide me to it because I've looked and looked and I'm getting frustrated

That's a gen 5 pcm, the process is different but it can be done

Depends on how aggressive the timing retard is, but if you have HP tuners you probably deleted the cats anyway 🤷‍♂️

Apply one change at a time to rule it out. Auto or manual? I've seen a lot of issues with auto cars

@@CanyonTunedit’s manual

@@CanyonTunedwould there be a reason to bleed from 0 downwards through the chart a little bit i’ve seen some people do it and some people say drastic changes can cause drivability issues without blending

Did you change the idle under/overspeed conditions? If so that could be causing the rev hang since it's overcorrecting on throttle closure. Log the car while it's happening (especially TPS % and timing) when the issue is occuring@@colincornell4261
