Gotta pick one. I see EFI Live getting the nod because I can convert to Speed Density easily.

Discuss.

 

LSJ - HP Tuners
LE5 - EFI Live (allows for VVT control, which I don't think HPT does yet).

 

On an LSJ, its a toss up. Neither can do more than 215kpa in speed density and I'm not sure how many tables EFILive supports for the LSJ right now.

The LE5 is a different story.

 

i really wish i had money i'd get efi live in a heart beat .. then again i have a 2.4 so efi live >>> hp tuners

 

As for tables, they support a little less then 1/3 of the tables & parameters for the LSJ so its not really a tossup at all as functionally we win hands down.

As for LE5 we offer some 400+ tables/parameters so you definitely aren't left out in the cold there either although I would like to know how many tables they offer in comparison.

Also keep in mind you could tune 4 LE5's with our software to their 2 with your initial purchase and our's is far less expensive by several hundred dollars in most cases.

 

Sadly the customer service sucks

weve been scratching our heads trying to figure out why the pcm commands half pulsewidth on injectors then doubles it in the blink of an eye...especially on the high power lsjs

Ive been asking for an explaination of this on the hpt forum since october with not a single reply from anyone at hpt

 

Both - HPTUNERS! Don't even mess with EFI live or LS1 Edit.

 

the biggest benefits for efi live are for the le5, and credits really shouldn't be the thing you're deciding on it should be on what does the job better

 

Sorry but none of us claim to be expert tuners, we make a hardware & software product, in the case of your injector duty cycle doubling, remember injector duty cycle is simply a calculation off of injector pulse width & rpm so injector pulse width is what you really need to be focusing on and why the computer is having to command 2x as much fuel from one cell to the next, you'll notice in your logs a lean spike right at the point where the injector duty cycle doubles so the computer is obviuosly compensating properly for a lean part in your tune.

Now, whether thats your PE table, maf table, VE table, OLFA tables, or your IFR table limits(which im sure your using injectors rated at larger than 62lb/hr) im not sure, it could be all of the above or just one of the above thats throwing things off.

The portion in your maf table where your going lean



Is exactly the same portion of your maf table where you COMMAND it go lean


Coincidence? Who knows, but im pointing it out.

As for tuning help we really can't help all that much for liability purposes because if we give you bad advice that won't have a happy ending.

We try and support our hardware & software if you have issues but the community is there to give you the tuning advice, I just try to plug in my .02 when I have the chance or have the experience.

That is after maf tuning the car 8 times...the car goes uber rich then BAM uber lean...that lean out maf is before the change over point and in the rich region...no matter how much lean out i command it still goes rich...same with the lean portion...no matter how much rich i command it still goes lean.

Look at the log of the run (its the one on hpt):


See how the injector duty cycle doubles for no reason...actually it goes normal...then just cuts out then instantly returns to where it should be. We have multiple cars with this problem on this forum and no one wants to explain why it does it.

Trying to fix for that little joy is why my maf curve looks screwy

Look at the ve as well...it goes up but fueling doesnt...car refuses to deliver fuel there for some reason

But why is it running half IDC for 3 cells then finally catching up at 10k...I personally think its something to do with how the maf is scaled in 300rpm spurts and how it interpolates data between them. Im using the same techniques that worked flawlessly when my car was supercharged and now that im not its all messed up

car will be back together soon and I can try somemore then. I just really want to get this resolved...im damn near out of tricks

 

VE doesn't have much of any effect on fueling at wot unless your maf is failed.

 

ya...i saw that after i posted

Here i changed it to maf flow and u can see its still rising with no correlating increase in idc

 

djt81185, my car doesn't do it. I don't know if that's only because I only have a t3/t04e or not. I'm also running a LS2 maf, dunno if that makes a difference in this case. I'm also only running 20psi right now.

 

Has the vehicle had a stage 2 reflash or an inline module or a tune or anything previously? I'm honestly not sure of exactly why its doing that as its not like your commanded afr is going from 14:1 to 11:1 at that point yet the pcm is telling it it needs to add more fuel so it is doing so.

 

you think that's bad, check out this one.
I have probably close to 200hours of tuning in my car, and same **** no matter what I do.

No stage 2 reflash, had a maf-t a LONG time ago but that doesnt permanently alter anything and its removed now.

The car has been tuned with the same HPT since the day after HPT released support.

Thinking about it now...It DID have a reflash for bad idle/stall in cold weather as part of a tsb. But it was supposedly for idle only.

The car is a turbo blow thru setup and has had the maf wires extended. thats all i can think of

oh yeah and on mine, same thing used a maf translator about 1.5 years ago on the car, been off ever since. No dealer reflashes (car has no warranty lol) running a blow through turbo setup also, with unaltered factory maf harness.

 

I used MAf-t for a while then had the GM satge 1 flash when it came out before HPT and got HPT when it came out.

 

Yeah but yours isn't doing it

Just trying to find anomalies

Is your's doing something similar?

Did it do the same thing with your stock tune?

When did it start doing it?

 

Just letting ya know. AFAIK it's only happening on turbo swapped cars. Mine is turbo swapped with a different Maf and not doing it.

 

I think everyone with a turbo swap needs to swap to a different maf then

 

will be doing that as soon as the connector comes in

 

Eh, I can show you it happening on supercharged cars as well. WSFrazier had the same probelm.

 

hey man i have some questions to ask you do me a favor and im me on aim digital0785 or pm me .. thank you very much

 

Indeed I did, fkn annoying. Fast cars imo.
