Default delta dash tuning

hello,

Did some searching with "delta dash", but I didnt really get a straight fwd answer of what I was looking for.

My question is: Can I use delta dash to improve my tune when I put higher octane fuel?

what Im getting at is, I am switching my current turbo( SBR gt30-12) for a 20g and getting a ecutek tune on 91. Im not a big fan of piggybacks and I really dont have much money either to buy utec or something similar to be able to do multiple maps, so I was wondering if the user tuning capabilities of the delta dash would give me any improvement when using 100 octane.
From all the research I have done, the standard 20g isnt all the efficient after 20 psi or so, so getting a custom 100 octane tune isnt going to yield crazy results anyway, but I would like to be able to benefit from some 100 octane everyonce in a while. ( like 3 or 4 times a year)

Does anyone think I can gain some extra power using the tuning feature?
This isnt the only feature im interested in the delta dash, I think the logging and road dyno are pretty cool too and would be using these, but my decision is heavly based on the fact if I can get some gains with the tuning feature.

PS. not looking to be the fastest, just want to squeeze a bit more top end if possible.

thanks guys and good day.

DD can tune, but IIRC the adjustments are made globally. meaning it chages every cell in that map, you can't change just a handful of cells. This isn't really a very proper way to tune.

The 20G will like race gas very much. You will see a very healthy improvement with race gas over 91.

I would personally suggest one of two paths: either getting alcohol injection. Or getting a accessecu protune, so that you can have the reflash reliabilty of a daily driver on 91, and have anther map for the race gas tune.

Or sell your EcuTeK license (ECU), and get street tuner. the Street tuner is self tuning reflash SW.

Or look into the openecu flashing options (the free SW).

I was using the live tune feature of the ecutek when I first started running meth injection. I was able to pick up 30whp and 40tq from just adjusting the open loop fueling,boost and wastegate duty cycle. It was ok. I finally got a full blown tune for my setup and picked up another 10whp and 20tq with a much better looking curve.

You can pick up power but it is not optimal.

If the street tuner option existed when I got my Ecutek I would have gone that route instead.

not optimal as in "not safe" or just not the most power?
Im really not looking for the most I can squeeze out of 100 octane, I just want to gain a bit of power in a reliable way.
was this much better looking curve a 10 whp and 20tq through the whole power band or top end?
Also, how did AFR look with your tune and the custom tune? was your tune unsafe?

Im on a tight budget, and spending money on the new turbine, EWG and tune is going to take up most of it. Would you vote against not using the delta dash at all?

It was a safe tune. I did a lot of logging and the knock correction looked good. I also have a wideband an egt gauge to keep an eye on things. The "real" tune was better in the low end because of the ability to pull out more fuel as the turbo was starting to spool. With the ecutek user tune you can only adjust a percentage of the difference from stoich while in open loop. My tune was also better in the top end because you can only pull out so much fuel using the Ecutek. With the smc kit the pump pressure is progressive. Once I got to about 20psi I could not pull out enough fuel. With the live tune I could only pull enough fuel to get to 10.8 afr. Now I run at 11.5.

yes, I do have ecutek, this is why im leaning towards this option.
Im not going to be using water injection, just plain jane cali 91, and I dont go to the track as much as I would like to.
I have had my car tuned for 8 months already and I really havent been dying for a race gas tune, and selling my ecutek ecu and purchasing cobb with a protune isnt very cost efficient for me as I would most likely have to buy the AP, get the tune and then look into selling my ECU.

it seems that the 350 dollars worth of delta dash isnt a complete waste, and that the investment in logging capabilites will be worth the investement with the slight boost/ timing adjustments I can make.
Do you regret having the DD?

I tried to tune using only the Delta Dash for logging and lost a motor. So did a friend. It doesn't have great resolution and the knock reporting is binary instead of incremental (knock on/off instead of knock counts).

It was a decent tool for its time, but now there are many free loggers/flashers out there not to mention UTEC/AP's are cheap.

If you already have a tune and want to simply check your AIM, advance multiplier, and crude knock, then yeah it's a nice piece.

cool. Im starting to understand a lot more on how the DD tuning feature works and Im starting to think that its not really what im looking for. Although the logging features are nice, I already have DL'ed a logger, just need the cable and seems from all the other people I have asked, that its not ideal to tune at all with it, but its more to make small corrections to a current map.
I guess Im going to skip on the delta dash for now.
thanks guys.

[quote=TypeC] knock reporting is binary instead of incremental (knock on/off instead of knock counts). [quote]

the knock signal is binary and you have to be sampling from the ecu at the exact time it is happening to pick it up in the log. It's a worthless item to log. But if you log knock correction you will see where the ecu has pulled timing because of a knock event. The amount of timing pulled correlates to the amount of knock detected. Its not as nice as how the UTEC reports it but it still works.

That being said the free software from tari.co.za does just as good a job as ecutek. Its not that one performs better than the other as much as one is free and the other is not.
