I have had a change of heart lol.

 

im here! haha just messin.

this sure looks good for the lnf's

 

B.S.

 

This is really cool. The one thing the LNF platform always needed was to do away with the friggen MAF sensor. Tuning by Manifold air pressure is the way to go.

I believe this also means that if a stock LNF were to be tuned by this, aftermarket mods added later may increase the horsepower, at least more substantially than the original setup lol.

 

subd

 

I should've bought the cable...

 

It'd be great if this could be made to work with hptuners.

 

Yeah this thread isn't about who tunes better, it's about the features of the software. No need to compare tuning abilities of anyone in here. I appreciate you guys keeping it civil.

 

I don't know that it wouldn't. It may be a similar situation as we had a couple years back when Trifecta had access to more tables than HPT and BYT was doing those layer tunes. This might work the same way.

 

Well if it is (like the combo tunes) and if the ECP works like u say, it will be an insta-buy. Lol.

 

Why would I spend $200+ on a cable when the Red one for $150 will work?

 

agreed.
i spoke with vince about that exact subject 2 years ago haha.
i'm going to be beta testing this today.
will post more info later/vids and how the car runs.

in theory this should allow for turbo swaps and all that with the on the fly ecm adjustments based off the iat, map and 02 sensors. i'm excited.

too bad our os/ecm doesn't support alcohol o2 sensors or we'd able to go back from e85 to 93 with ease.

 

lol What?

I may be misunderstanding what you meant, but I said that your red one would work fine, so no issue.

In my case, I've got LSJ customers and such too, so I can't use the Tactrix, for instance.

 

I think this is still possible in some way, shape or form. There has to be a way to integrate the signal from am ethanol sensor into our setup. May require some extended hackery though. I think with enough money, Vince would find a way.

 

its not unfortunately.
our ecms don't have an input for it.

 

uploaded the ECP tune.
it's still in beta. I'm awaiting to hear back from vince on what he sees as far as results go.
everything idled and started just fine.
here is a video/pull....err as good as I could get it with one hand.
i took a lunch and drove to mexico.

Im also still waiting on Vince for the revised file. But to be honest it pulls soo much better now that this tune fixed my P0101 ISSUE.

 

interesting.
i didn't have any maf issues.
i should have unplugged the pigtail going to the sensor to show that it really wasn't reading off the maf and there was no engine code.
you know...for the naysayers.

i can understand why it runs better though. that po101 would make it run like pewp.

 

Yes and its done that for a year. I put a smaller filter on (i ordered the wrong one) on my dejon intake and it sent it for a loop. now...its fixed.

 

Yeah, I've been having some troubles fighting off KR with my big turbo setup on hptuners.

 

Knowing what I know about the complexity of the E69 controller in the LNF I am very curious as to how this works. Speed density on an LNF could be done but with 600 tables in the ECM that control fueling it is not like SD tuning a LS series car.

I have seen 8 different LNFs with P0101 codes and in each case the cause of the P0101 was a boost leak. SD tune will just be a bandaid if you have a boost leak.

 

With enough money it can happen.

 

Yeah, the knock sensor sensitivity goes up with load if I remember right (it may have been the MAF tables... it's been a while since I had talked about it with him), so skewing load will crank up your knock sensor sensitivity to where it'll sometimes be hearing things that aren't really knock. This in turn causes driveability issues because it randomly pulls timing when there's no need to.


When scanning with my Dashdaq a while back, it revealed that there are Speed Density capabilities within the ECU. I'm wondering if that's what it falls back on when it goes into limp or malfunctioning/disconnected MAF modes. Perhaps he found a way to force it into that mode while making it more than just open loop.

I haven't been working with Vince on this particular project, so that is my own speculation.

 

Although this may not be a possibility, we have been toying with the idea of select-a-gas

basically select-a-tune but instead of low boost you'd have 91/93, instead of high boost you'd have E85

 

...But then we're back to the single tune days effectively. If Vince were to roll that out, he'd be best off to have a second way to switch the fueling so people don't give up their DD-mannered vs. power-focused tune selectability.
