Hey everyone I need to run this by a couple tuners before I think I'm going crazy here..

Originally when I had my car tuned 3 years ago, the very experienced tuner was telling me how I shouldn't enable this "honda ignition adjustments" when neptune was born at the software from ages ago I was unable to adjust the valves at the top of this picture.

Looking back at my original tune I didn't have this option enabled... GOOD.

so looking at this now it appears from my understanding that looking at this info if I were to enable these adjustments if I were to be making peak power at 4875 rpm @ 30 degrees of ignition timing reported from Neptune/my laptop/ tunerview IGN2 value then Actual ignition timing would be 24.25 degrees right?

so if I enable this option then reported timing will now be 35.75 degrees and cause a LOT OF KNOCK!

does anyone use this option? I have never tuned with this option in the past and the power output for my h22 was pretty close to what others had with similar mods and it leads me to believe that I don't have a problem with ignition timing. if I was off that many degrees of timing..

 

I've taken quite a bit of time to explain this all to you. It's enabled in the stock Honda code by default so it comes enabled in the software as well. It's BAD, not GOOD, that your tuner disabled it and didn't compensate for the lack of timing via your maps. Almost everyone has this option enabled unless they're advanced users who have compensated appropriately for disabling it. I've covered everything you're asking here in our emails. Please re-read our email conversation.

 

I have disabled this on maybe 1 out of the MANY cars that I have tuned with NepTune in the past few years.

There is no reason to disable this as it is there and is how Honda intended the timing curve to be adjusted.

If you are having any issues with the tune you can adjust the actual ignition table or the dwell table to suite your needs. But I can tell you that I have NEVER had to touch this table when tuning any setup, including many higher HP cars.

NepTune just allows you to view this table and "actual timing" value.. not just the table timing value, like most of the other software out there.

If you are not comfortable viewing the "actual timing" value then don't pay attention to it, just tune off the table value and keep the ignition adjustments turned on.

I assure you that if you disable these adjustments on a stock GSR using the stock P72 tune the car will run horribly on the top end.. showing you that Honda did intend to have these adjustments there.

 

HRtuning this is no offense to you, but I wanted to get a second opinion on everything.

I understand what it does now thank you for explaining it. I need to put this on the dyno to exactly dial in.

However I find it interesting that my car still made 170HP and 145 tq with timing off nearly 10 degrees according to the compensation values listed along with my timing at 31.5 degrees... I find it hard to believe.

 

I think you should put it on the dyno with your current tune with ignition adjustments off.

Then load a stock GSR timing map on there with the ignition adjustments enabled and see the comparison.

Or just do it on the street for "fun" and see if you can feel a difference.

And I do believe that I explained the SAME EXACT thing to you about 2 years ago when you first started tuning with NepTune.

 

You have to be crazy to think I would remember something someone told me on a forum two years ago when I was learning how to tune.

If you have the post id be curious to see and re read what kind of stupid things I said back then when I didn't have much experience, but everyone has to start somewhere.

I could post the tune I had from 3 years ago that made 170hp with the ignition adjustments off for you to look at. I assure you there is no way I could have made 170hp with the timing nearly 9 degrees in the negative... when you think about that it sounds stupid.. although if you want to take a look at the map by all means take a gander at it.

Edited Base Map2.ncl that map made 170hp, ignition corrections were disabled during the tune, and all my tunes from then on.

But the thing is an H22 is not a B18C so I don't think the timing maps would be identical, unless the timing is more related to similar compressions of that engine vs displacement... you sound like you are the expert here you can tell me why.


Feel free to call the BS flag and prove me wrong. I just dont by it.

Thanks for your time.

Aaron.. you use to IM me on AIM all the time and ask me questions like this. UNCGOLF25 ring a bell?

The H22 and B18C can run similar timing curves, I NEVER said it was going to be identical. I said to compare how the car felt on a stock GSR timing map with ignition adjustments turned on.

It seems I should've hammered what I was trying to get across to you 2 years ago a little harder.

 

What's hard to believe is that you're skeptical of advice from an experienced tuner who wrote the software in question, and another experienced tuner who's been using the software for years. I've done my part and spent a good amount of time explaining. How you use that information is up to you. That's the whole basis of a user tunable system. Good luck.

 

That really isn't my point its just the numbers dont add up. I have seen posts from others who say about 31-32 degrees of ignition timing are had with a stock h22 and bolt ons.

I can't imagine having ignition timing 9 degrees would make ANY power, yet mine made 170 which is at the low end of the h22 spectrum due to bad intake, horrible DC sports headers, very restrictive exhaust. which leads me to believe where were the stock Honda ignition values grabbed from?

I take everyone's advice! but I also like to get others opinions as well. so its no offense to your skill set / knowledge base.

I can adjust so much before I actually need a dyno to tell me what I'm doing is correct.

Thanks thus so far.
