The other thing is not everyone uses the same settings in DLL so there is variance there as well. Do you use aero drag settings on the dyno? Does DLL weight matter since the dyno is already setting up load for the entered weight by the dyno operator?

I've also seen DLL logs go the other way on a mustang as well. I've seen way too much weird variance to depend on the DLL dyno feature for anything other than before/after comparisons with the conditions set as I listed above. This is all IMHO like usual of course.

 

you mean you're not supposed to do that??? waaaaait... i thot you said ur a toooner... :dodgy:

 

I prefer 6 o's.

 

^ nexxxxx timezzzzz

 

The problem you run into with using the HP calcs on a dyno is that the resistance to acceleration is no longer the weight/drag of the car, but that of the dyno's rollers.

Edit> On a load bearing dyno it's even worse... For obvious reasons.

 

interesting DLL data, I'm currently doing an e-flash tune for a 20GLT EVO9 FMIC etc.. 93 octane @ 23psi spike on stock cams.. this is a work in progress so it may be premature to show this but it looks like we're on the right track. I've since added another degree of timing since it was knock free and I'm waiting on some logs to come back but I think we'll be able to get that up a little bit on the big end as we lean it out up there.

the customer was interested to see how much we were able to gain over the previous e-flash another tuner on here did for him, hence the overlay. I'm finding that DLL is extremely useful when you don't have a dyno handy.

I can't wait to get started on my own car... if the 20g, fmic, ported mani ever show up.

 

it seems DLL is showing similar results with all these evos that have similar mods...
ive done a lot of logs and have used DLL and have seen in every pull same results on the same road it must be flat cause if it has a small incline you loose power and if it has a small decline you gain power and bettween a cold day and a hot day i have seen differences of up to 10wph as a max...
nj nice to know that you did a comparison with a dyno and dll 7% in hp is something he?
thanks for sharing razorlab

quick question guys....I have an evogreen that i picked up from ams about 2 weeks ago and installed it right away...I am running full bolt-ons such as HKS 272 Cams, Buschur Intercooler, buschur uicp, intake, exhaust, mbc @ 23 psi, my tune on UTEC, ported TB, ported intake manifold, etc.....it def. pulls a little quicker on pump gas, which is only what i have ran on so far, but people are posting numbers like 420 whp on pump gas....it doesn't feel like it though...any advice from you guys to make it quicker like diff. cam setup? or should i get ported exhaust manifold? It feels pretty quick thats for sure, quicker than 16g.....I went to the track and ran 12.2 @ 114 with 1.7 60' on 23 psi on 93 pump....is that a good time for the 20g on pump gas? and what other modifications should i consider? thanks guys!

 

I would say that's very low. At 17-18lbs on stock injectors and a tune for the stock turbo with the green and BPU+, I trapped 117.
