jdl catted header OTS tune ok?

For my latest revision, I'm using the JDL AVCS maps from Shiv. Previous versions, I had Wayno's stg2 v104 AVCS map. I haven't used Wayno's v104 map aggresively enough to come up with a concrete opinion (and I'm a rookie at this so I can't feel all the little details compared to a pro) but the JDL map feels a bit more smooth and had some pep when banging through gears in sport mode.

FYI, mine's a auto transmission. Oh and here's the latest log I cranked out today: http://www.datazap.me/u/gawesome/201...zoom=3209-3445 Still combing through the data but I still have a tiny bit of flkc and knock correction on first look. AFR and IAM looks solid to me though.

You need to try the 107 and overrun tables.

I didn't check your thread in a while...didn't know you updated your tunes to v107 already!

What people are calling the "jdl specific avcs tables" are simply the OTS UEL E85 tables as I said before. The newer maps are much more sophisticated and nicer to tune and I would use them for both UEL petrol and UEL E85, regardless of brand. They are identical over 5000 rpm anyway, so the only thing that will change your peak power is fuel and timing. But don't listen to me.

You should copy di ratios, avcs, overrun maf, throttle and whatever else. Just use your own maf and timing already developed. I would recommend the OL and CL fuel tables too.

Thanks Wayno - agreed.

The only distinction was the different OTS AVCS Exhaust mapping for UEL compared to UEL E85 in V2.076 - which I already standardised to the UEL E85 values across the board (which also happen to be the original "JDL" values Shiv provided). I don't see the intent in the two different maps - my guess its just something that evolved.

I will get around to looking at the AVCS values in your maps - after I waste some more time playing with timing on Stage 1 tune

I can use without catted header JDL without tune ? Knowing that without tune not take the maximum power, but not matter to me.
I do not want to have engine problems misfeeds.
I do not like to change the original tune, I have fear of not going well.
To use headers without tune, not having CEL? injectors have no problems?
Very thanks!

Having a little trouble following you, but:

Catted header = you should be fine without a tune
Non-catted header = you need a tune, or else you will get a check engine light

There are no concerns with the injectors or anything else when replacing the header.

Very thanks

From all who are already experienced with this this year(when the weather gets warm and stays warm as my FRS is tucked away in the garage for the winter) i want to run a catted header as i live in a part of PA that i have to take a somewhat stringent emissions test, is it an absolute no-no to run the stage 2 OFT tune with a catted header? Or should i just stay with the stage 1? I know i'll still gain more power by adding the header, but not quite as much as would with a stage 2. What really are the long term affects of running a stage 2 with the UEL? I know the JDL is a high flow cat, so that should at least compensate for the stage 2 i would think. I have worked on cars for years and not trying to gloat, but i know a pretty good deal, but i'm still pretty new on computerized tuning and the fact that EVERYTHING on cars now goes thru the computer. I thank yinz in advance for your input. 👍

I have ran my catted UEL JDL headers with Stage 2 for over a year now, no issues. That being said, I changed the timing according to Shiv's numbers for the JDL UEL, and you NEED to data log every now and then to make sure you're not having any knock.

Some people say the cat will burn out eventually, but hey, wear and tear, right?

Yes it may burn the cat out early from what i've read and then thought in depth why it may. I do always run 93 so that should cut down the possibility of knocking/pinging. Do u just go on OFT's website for the timing maps for the JDL and download them to the tablet?

It is somewhere in this forum. Look for AVCS JDL UEL

Last time I checked the "JDL specific timing" had been integrated into the V2.076 tunes. Its now all the same - there is no longer any "different" JDL timing.

Feel free to check....
