Great write up man! Been at this tuning game for two years and im still constantly learning. That modified duration table made me eyes wide haha. Crazy. Takes time and dedication for sure. Patience is a needed virtue for tuning. I love when stuff like this comes up.

Mike I don't know if this has been asked yet or not, but if you take a UDC tune that you have written for say an 05 truck, then load it onto an EFI live compatible truck, will you be able to datalog the UDC tune via EFI to tell exactly what the values are and whether or not they are accurate?

Very good question! This is not the exact same scenario but close: On my personal truck (2006) I built a UDC "street" tune very similar to an EFI tune that I was running. I used EFI to data log the UDC tune and the results from the logs were very similar to the tune. Meaning that what I built into the tune was actually being commanded. This is true only up to a certain point on most tunes as with EFILive I can set maximum timing, RPM, limiters, etc where I want them. With UDC these limits are preset and not adjustable for the most part.

VERY good read. Have to agree with Crawfish Pot though. For anyone including myself new to EFI Live the possibilities appear to be endless but so do the disaster possibilities of trying to build maps for someone without the experience. Fork out the dough to the big boys who know what they're doing on the computers

I’m going to put this here in the hopes that someone reads it!

Long story summed up, I’m getting a new turbo to replace my stock in my stock/475 setup, and since it will be bigger, I assumed I would need a new tune. Anarchy is MIA right now, probably due to EPA shenanigans. So I reached out to hardway performance and they don’t think that more air equals the need for a new tune. Anyone think that’s actually true? Because I’m fairly sure turbo spool can be effected with a good tune, especially on these bigger turbos.

I was told you don't technically need a retune until you change the fuel setup. If you don't think it is at its full potential then yes a retune would be a good idea, but unless your setup is laggy then I wouldn't worry about it.

So one question is this, were you cleaning up all the smoke prior to the turbo taking a vacation?

Yep sure was. There was obviously smoke if I got on it hard before the turbo spooled up, but I wouldn’t not have considered the truck smokey by any means.

Well, if you were clearing all the smoke up when the the big one lit, then the you should be fine running it with the tune you have now, it will prolly smoke a tad more down low than it did before, but it won't affect anything after the big one takes over. If it is real laggy, then you may need some fuel pulled to help it lite, but I would run it and see how it performs before paying someone to get new tunes.

Sounds good! We’ll see how she runs and then go from there. Thanks gang!
