Performance chip reviews for 8s?
 

I am thinking of getting a performance chip. I am wondering if anyone has experiance with them in an 8. I have read through some threads and it seems like everyone talks crap without ever trying it. The only two people that have them that I have found love them. I had a chip in my last 4 cars. But they wernt rotarys.
Please only post if you have owned, tried, or been in an 8 with a chip. Thank you!

please delete this threade before you get flamed/butthurt then search cobb access port

There isn't any "chip" for improving performance. There is only 2 good options. The Cobb Accessport and the Racing Beat reflashing service. Both cost considerably more that these so called performance chips that you find on ebay. But hey, at least they work and won't destroy your car.

Perhaps start with my New Owners thread: https://www.rx8club.com/new-member-forum-197/new-potential-owners-start-here-202454/

It has this bit in it that you clearly missed. What else did you miss?

Even a 'super moderator' has missed the fact that this foolish thread is also in the wrong section all together. Please move this from GENERAL AUTOMOTIVE to wherever it belongs.

the trash?

I don't know why everyone is being so rude. I asked if anyone tried it. If you have tried it I want to know. I am not asking for the opinion of those that haven't even tried one. I have used them on other cars, and I got results. So if you did try and it worked, or did nothing, or harmed your car I would like to hear about it.

It doesn't work, period.
Besides, it's something easy to search for on this board.

There is actually a thread devoted to stupid questions - you should have asked there .

I'm staying out this one

You have to understand what a "chip" does, what our ECU does, and how they work together to produce results.

Chips alter the signals from whatever sensors, adding a level of resistance, voltage drop, etc... so that the ECU sees different signals coming in, and makes it's built-in adjustments to run as "intended" at the signal level it sees. In some very poorly or conservatively tuned cars, you can produce more power through this faking. However, chips don't have the full range of dynamic ability to adjust for all RPMs at all load levels, throttle levels, gears, and speed, so it simply won't be able to help you everywhere, just some places. A chip will NEVER be as good as a full ECU tune, either OEM ECU that is retuned and reflashed, or an aftermarket ECU. The ECU simply has the dynamic detail needed to be that much better.


With this in mind, an ECU tune alone on a stock 8 can give you as little as ~3hp, and as much as ~8hp. For $500 or so, plus tuning. Expensive for the gains? yes. However if a chip CAN NOT reach the ability of an ECU tune, then guess what? You are probably LOSING power, assuming you don't brick the ECU and have to replace it at $1,800 a pop. At best, you will stay neutral.

There are also other things like redundancies and failsafes on our ECU. Even with an ECU reflash, people testing out the extreme lean burning under light load couldn't get it to stay lean, because the ECU was still picking up that it was too lean, even though the target maps said to be there, and it would correct back into normal AFRs.

IN ADDITION, the rotary engine is VERY sensitive to timing, fueling, etc... and it's very easy to destroy your engine by nudging the very narrow bounds too much. Even naturally aspirated. This is NOT a piston engine, and you CAN NOT assume that the "truth's" you learned modding a piston engine apply equally to a rotary. They simply don't.



No, a chip will do nothing but cost you money. Hopefully only the cost of the chip, but entirely possible it would cost you the ECU and/or engine as well.


It isn't worth it to even test.





If you ignore this advice, feel free to go waste money on it. Let us know how bad it gets so we can laugh at you for getting good advice and then ignoring it.

No...i haven't, and please don't. :banghead:

I got one decent responder and the rest... Are you even reading this thread?! Thanks for the waive shit why not to. I want the opionions of non testers, but austin I ONLY WANT responses for people that have tried one. Still to this point everyone says no without sent real results of sucess our failure. I understand this is more than an piston engine! Sigh....... But not one of you is actually answering t he question....who has tried it? What were your results? My rx8 is still under warrenty and I am about to buy it.... Only because it seems as though everyone says it won't work.... But no one has any experience with it! I will put a new thread up about it... And I am new.... Stop being jerks, dicks errogent, rude our what ever you want to call being an ass so people can actually have a conversion! If you don't know/ aren't willing to explain then don't respond! I am about to cancel my res. to circus circus! Be helpful not condensing!

You're calling out names while you're the one acting childish...
A chip won't work on most modern cars, rx8 included. Even in the obd1 cars where they did something they didn't do anything good.
You say that you want opinions from those who have tested said product, failing to realize that that is not always necessary requirement...
Anybody who knows how our PCM works can tell you that a chip won't do anything good at all, Riwwp was pretty clear in that regard and went as far as telling you why.

Chips work by "fooling" the ecu as he said. Unfortunately the best comparison is that of having a drunk ecu trying to dodge objects being thrown at it. Unlikely to succeed. Try doing calculus when drunk before buying that thing and see for yourself.

People are genuinely trying to help by telling you it's a scam/doesn't work.
Think about it, is that chip really going to able to alter, monitor and control everything it needs to in order to make power or better mpg?
If you think it does, you either don't know what your doing or are really naive and I which I have some magic beans for ya.
Or your just trolling?

Here, go buy one of these and stick it in your intake. It'll smooth out the flow of air across your MAF and increase your HP by 25% and your MPG by 10%.


I've also got a bridge up for sale...

No shit ... how much? Where?

You know newb that you are suppose to post that in the For Sale sub-forum
LOL heheh

Ummm so how much?

Just a little one I keep stashed in my backyard.

I'll let it go for an even mil.

THIS ISN'T JUST OPINION! THEY DO NOT WORK THE SAME WAY THAT RUNNING DIESEL FUEL IN A GASOLINE ENGINE DOESN'T WORK

We don't need to actually test diesel fuel to know that it won't work, and testing it has a pretty damn good chance of causing significant damage.

What you are doing is the equivalent of going to a PC software forum and insisting that people only respond to you with their experience of how well pouring water into their running PC case worked for cooling it down. Anyone that is STUPID enough to try it sure as hell isn't going to have the guts to post about how stupid they were.

Go ahead and be a <withdrawn adjectives> that refuses to listen to the advice of people that know. Buy it. It will also mean you will never be back to the forum because there would be ZERO chance that you would be willing to face the embarassment, shame, and flaming that you will get for doing it anyway against all information to the contrary.

Ummm I've been over that bridge a few times ... the weather has always been crappy.

Give me the San Mateo bridge as well, for 1.5 mill and its a deal


And OP don't listen to RIWWP ... that dude has no idea what he is talking about.

Buy the chip ... test it out and report back

Why bother with a chip at all?

Buy one of these at your local Radio Shack...

And wire it to the positive lead on your MAF sensor. When splicing the wires be sure to just wrap them without any thought or concern for additional resistance because you really want as much as possible to arrest the flow of data between your MAF and the ECU. Also I recommend duct tape for covering up the splice. The silver tint adds bling increasing the resale value of your RX-8.

You can also do something similar with the IAT lines integrated into the MAF sensor. Intake temperature is totally over rated.

And one final spot to stick a resistor is on the barometer sensor right next to your air pump box to trick the ECU into thinking its running under water. Just think of all the extra cooling you'll get!

LOLOLOLOLOL
Now that there is funny

Hey! don't knock it till you try it! EBay fly by night hacks have invested literally dozens of minutes into the development and rollout of these modifications.

I'm just giving back to the community... offering even more affordable hacks without all the extra hype (and shipping charges).

Pffffff don't try and bullshit me,
Does it come with the bridge or not?!

lol
