BWR Supercharger Software Poll

[Zinhead]

With the group buy for the BWR supercharger going on, I was wondering what software BWR users prefer. BWR offers the PES tune for $400, or you could use the CharlieX Katana tune for $600. Charlie's Katana tune was not done on a BWR, but people are apparently using it. Post any experiences you have with either tune on the BWR.

[EBTurbo]

I know it might be a bit expensive compared to PES or Charlie's flash but the EFI 1.2 is a viable option for the BWR kit. Other bolt ons cannot be taken advantage of unless custom tuning. even sometimes then the factory ECU will correct out the tune. Im not saying the EFI is any better or worse then the factory ECU reflash. it should at least be considered as an option for this BWR kit.

The correction is simply a feedback correction to attempt to keep the VE tables set to the desired AFR , the EFI 1.2 should do the exact same thing if it uses Base AFR's and not just VE correction, unless a wide band is used that can correct the fuel tables to reach the desired AFR's as we do on some cars.

But even that does not guarantee that the correct AFR will be reached, since some modifications may require a different AFR to be set and the ecu won't know how.

Its the correct thing to do, the whole point of the feedback is to let the ecu know something external has modified the conditions the ecu was set for, unfortunately when you change a parameter that the ecu , including aftermarket ecu's, can't measure, it will not correct properly and will require a retune.

Unless you're saying the USA EFI can detect say a header and retune it for correctly without intervention, (unless using a wideband which should only correct it back to the preset tune, not nescessarily the most optimum for the header, which the factory ecu can do as well ) ?

The factory ecu is no different in this respect to any good ecu that can do feedback correction, this myth has gone on long enough

[EBTurbo]

I was just saying that the EFi is a viable option if other changes are going to be made other then just adding the BWR kit. Both have their place in this market and both do what they do very well. I have nothing bad to say about your tuning. With the EFI the end user has a more control. with additional bolt ons or engine work those mods can be taken advantage of.

[charliex]

My tunes can be retuned just the same as the EFI USA's, there is no difference on that part, the only difference is that the end user can retune the EFI, and so far only a few places can retune with my software, but thats changing slowly as we try to add more places.

You're not talking smack about my reflashes, you're just perpetuating the myth of the closed loop corrections not being a good thing or somehow unique to the factory ecu, which is what i've corrected, your ecu ought to the exact same thing as the factory, otherwise you'll end up with custom tunes for cars with different fuel available, e10, e15, wear and tear on the engine, and vacuum leaks, etc, without those correction abilities the tune will be wrong.


Re the original topic i haven't determined whether or not to offer a flash for the bwr kits yet anyway, at the moment i have done a few of them, but at basically sold 'as-is' for them that needed it.

So Charliex, could you tune my 07 Elise if I go woth the BWR kit?

Charlie,
Is your hesitation only that you haven't had time to play with a BWR on the dyno? If so, if we can get a volunteer for tuning, would that resolve things?
Could we get a speedo correction along with the supercharger tune? (2005 Elise).
Thanks,
Joe

[stinkyonion]

Put me down for a charliex tune for my bwr supercharger too when he's willing.

I would think someone (or a group), would need to pay him (and pay for the dyno time) to do it and provide one or more cars with the BWR.

[WCS]

I know that Charlie's expertise is highly regarded and I would love to have the tune for BWR as an option (I'm in the group buy as well).

However, the BWR + PES tune kit has been on the market for some time, and I am wondering whether there is anything wrong with it. Plus the CARB application presumably uses PES tune right? Can anyone elaborate? Thanks.

[Ol'Racer]

Came across this post by Optimus. Regardless of whose tune it is, it looks very good to me. I think PES or Charlie would be satisfied with the charts. I've had many dyno tunes on other cars and I would be happy with the readouts.

What are the differences between the 2 tunes discussed. Does Charlie have some trick hidden options or are they basically the same? In other words, "is watcha see is watcha get" on the dyno? So, if the dynos were about the same is it a coin flip? What distinguishes one from the other? Just curious.

I purchased the BWR kit because Sector's was out of stock at the time. Fred was also really cool to deal with. A buddy and I installed the kit within two days with the cam on! Relocating the alternator was the hardest part.

Anyway, so far car has been running great. I have put almost 3K miles on the car with the supercharger (car now has 10K miles on odo). Lately I've been hearing people having trouble with the tune and blown motors which got me a little nervous.

So I went to the dyno today and did a few runs. Do you guys see anything that should be alarming??

I'm in Fresno, CA where it's been almost 100 degree's everyday this summer. It was 85 in the shop when I did the runs.

There's a lot of people running the PES tune and are fine. I'm sure it would work fine. I just enjoy Charlie's tune more.


If I did not have Charlie as an option, I would happily run the PES tune. One of the benefits is that Charlie is actually willing to travel to custom tune which is cool. There's a lot of guys in this area who still want a custom tune from him (hear that, Charlie???)


I've seen Charlie's tunes on the dyno and they are some sight...

[steidley]

if I could also get the speedo fix, I'd go for the extra $200 bucks in a heartbeat. (I'm still on the fence about the kit, but I"m looking for excuses. You know, pay $4k to fix the speedo, but you get the supercharger thrown in)

That's what you can tell your woman.... It's for safety, of course

I've been running the PES tune on my BWR for ~ 6 months. It did take two reflashes to get the AFR's in the proper range & though she's running fine, I would certainly be interested in a custom tune by Charlie.

Mike's correct, there are many folks in the NY/NJ/CT area who would more than welcome a visit from Mr. X! Especially now with this BWR group buy.

I agree....it would be awesome to combine the BWR kit with Charlie's tune...I'm hoping that this is a viable option, as it is one of my trepidations about the GB....

It is very interesting, and I think that on any case, the customer will be captive from the selected supplier.

On every proposed supplier here, which are PES, Charlie or DRS (EFI) are small or quiet. Charlie and DRS are small company, and in this case, it can be possible to maybe sometime to have a lack in support. And PES, maybe sligthly bigger (I just don't know), could maybe give better support, but they are quite low profile down here on the forum.

Other than the program itself, if you are leaving at one block of one of those, this option could be the best one.

Probably, I can find very nice comment for every one, and maybe not that much bad comment about every one since no customer will risk to compromise his relationship with his ECU or reflash supplier.

I have a friend (not me, to be clear, me I am wating for something else)waiting for his ECU troubleshooting (maybe from one of the 3 cited supplier), and it was just difficult to have any feed-back from his supplier. Do you think that this guy will do a post in regards to his supplier no response, of course not, it is a captive market.

The best solution will be the one which you will be able to have the best support.

Where I am living, to have the best support, I should go with Hydra Stand alone because the best tuner on my area is specialised on Hydra set-up. But since Hydra don't have any program for BWR or Katana or Forcefed kit, it will be very expensive to have the tuning done.

Of course, what I said is not my opinion because I will never take a risk to compromise my relationship with the previous, or my present, or maybe my future selected supplier.

I have a 2006 Elise with the BWR kit and PES tune installed by HRM.
I have had a constant emissions CEL. It has been cleared several times and keeps coming back.
However, I also have an Arqray twin exhaust, but I never had the CEL until the SC was installed.
The mechanic that used to work for HRM (he is now working out of another shop) checked it out and said the car was running a little rich.

I would give the CharlieX tune a try and in fact I plan to do just that this this winter while the car is hybrinating.

[Johnny B]

The CEL has nothing to do with the Arqray exhaust.

I have the Arqray twin on my Katana with Charlie's tune and have no CELs.

Agreed, I'm in Lyme CT, CharlieX, come on down!
