did anyone ever figue out why that occurs?

**** 'em. :D

 

the injector pulsewidth as measured on the scanalyzer drops by about 25% from 850 to 1K rpm......

 

First, feel free to PM me if you need a test RX8 (I'm in East Orlando) and my RX8 is completely stock. I know a fellow member in Ocala said he would donate his car for testing so if you need another one let me know.

I read all the Inter-X stuff and while it's pretty much the best thing out there right nowthe price keeps alot people (myself of course) away from such a product.

So, if you could give us a aftermarket flash giving us 10-20HP and costing about $500 I'd be all over that. So...if you can make this happen you will have a huge market.

I don't know the technical side of this but a good $$ per HP number will gain you more customers than you could handle...lol.

My wife is almost due with our first child and I'll be about 2 weeks off at my job so that might be the best timming since I do "need" my car daily. During my vacation I could use my wife's car so you all could perfect your ECU tune.

2 Questions:

1) Is there a tunning for dummies book cause even if I bought this I have no clue about all this technical stuff

2) Would you have to redo your flash with each NA mod? I'm guessing yes to maximize your power.

I'm always late to this talks...lol, but again PM me if you would like to test it on my 8.

 

You are missing the point! If they can pull off a tool that will allow you to download the current A/F maps, settings, etc, modify them, and re-upload them to the factory ECU; many people won't care whether it comes pre-loaded with maps or not. The fact that it'll be a once and for all transparent engine management unit makes it worth it in itself. Just take a look at the folks from APR & Hondata...the ability to keep all the goodies that the factory ECU has + the flexibility to adjust it for whatever you do with in terms of upgrades.

That alone, IMHO, is fantastic.

 

^^ exactly! That's why I always scratch my head when someone else talks about wanting a motec or other standalone/piggyback ECU unit.

 

Yes, but as engine speed increase by the same 20-25%, fuel economy remain almost identical. You guys should think before making such statement of improved fuel economy.

Yes...getting a flashing tool for our cars would be GREAT, but remember the people like me that just don't know that type of stuff would not mind (like with dmp's wife's gadget) for them to ask me certain questions and make a custom map for me (1-3 of them).

I understand and agree, just getting a tool that will allow us to flash our cars would just open the door to a whole new world for the RX8.

I just hope they don't end up selling this thing for Inter-X type prices. For some reason because we have a rotary engine we are forced to pay a premium for aftermarket stuff while gaining only slight HP gains. Yes I know, there is more to it than peak HP…yadda yadda yadda, but overall I think our aftermarket is severely overpriced.

Again, there are members here with deep pockets who think 1.8K for an ECU piggyback is money well spent but while I respect and am grateful that we have something like the Inter-X...I'm priced out of the fun so getting something like dmp's little tool would be great.

 

Oh yeah, that's the thing since our 8's run pretty rich down low in the rpm range not only could we pull out some more HP but our city fuel economy might get a bost also...maybe even highway.

Since I'm satisfied with my 8's fuel economy, if I could pull out another 1mpg and 15HP for $500 or so...I would be (like I said) ALL OVER THIS PRODUCT!

 

Actually, in low rpm / low loads, the 8 runs really lean.

 

Personally I dont care about the mpg I'd rather see more HP.

More hp = Less MPG is fine with me

 

but what about more hp and mpg?????

beers

 

Now that you said that, of course that sounds perfectly correct...gosh, I swear I heard someone say the opp....or, was it just that they made it leanER....

I don't worry about it much, but if I got 15 more HP but lost 3mpg it would not be worth it. I just refuse to get SUPER CAR fuel economy at the level of performance I have with my RX8.

So, I understand what you are saying...I don't worry about it cause I get 19+...easy, but like Swoope said...why not add HP and fuel economy???

 

It is fine if they can add both, but I dont want them to try to sacrifice any power for a little better fuel economy. If I had to pick one I would pick power.

 

From past experience, usually there is a gain of performance and fuel mileage (as long as driving habits remain the same). Sometimes your driving habits change when you get a increase of power (the fun & excitement of extra power) which could show a mileage loss. However, once driving habits get back to normal, mileage usually improves.

 

Never said anything about fuel economy...I do know that it idles better there though!

 

jeff did tho

 

Anyway...how does decreased fuel at higher RPM end up even in fuel consuption???

 

Yeah, that's about what I've heard...you gain a significant amount of HP (15HP let's say) and maybe pull out another 1mpg in the process.

But, I'll settle for the same fuel economy with more HP. I can't wait to hear what you are able to do.....

By the way, would you need a new flash once you add more mods? I'm guessing yes...

 

Ideally, yes a new flash would allow more precise results. However, with some modifications, you are able to get away without it. With some other modifications (injectors, forced induction, etc...) there's no choice but to update the ecu program.

 

OK, makes sense...

So what's the current status? I don't want to be pushy...but like most of us here we are REALLY happy you are even attempting this. I hope the best for you all and hope to be a customer soon...Thanks for your efforts!

 

We've tentatively set up a couple cars to come in this week (the first being tomorrow). Please keep in mind, this just makes us a step closer. There's no telling how soon until a finished product is available, but we should have a much better idea after these two cars come in.

 

Yeah i here ya man, Alot of ppl here do have deep pockets, but for alot of other ppl who go to school and have a job that doesnt pay much, the mods for our cars are kinda $$$$ but hey thats how the market is at times

 

Fastsvtss,

would we use a computer program to dial in the maps and other settings we wish to change on the ECU, then upload those settings from our computer to the handheld unit, then flash the stock ECU?

Is that process correct?
