Hey bros, just installed Unichip on my 8, Low revs are now excellent....definitely feel gains to in the high revs. Going to do further mods to the exhaust...and proceed for a dyno thereafter. Hope to post up the dyno charts soon. Cheers!

^^^what he said. I've never heard of that.

I think he talk about this product

Any idea where to install this unichip? wats the costs of it? thanks for sharing the info

I'd compare it to an Emanage, but with a price tag close to an AEM EMS. And only a Unichip dealer can tune it. It was a POS for the S2K...I hope it's better for the RX-8...

its a dumbed down version of the CanZoomer piggyback in my opinion. With no customization. My problem...how does it no how much to adjust the MAF? Even in the CanZoomer piggyback we have to tune it to our vehicle....

I don't see this unichip working that well. Even with the cz / e-manage, it only modifies the maps above 5000 rpm because under that point the car is in closed loop and self adjusts the fuel map getting it close to 14. If the unichip leaned it more, it would not be good, and if it made it richer, you'd just be burning extra gas and choking the engine.

does the unichip remove the rev limiter??

Neon

Yup, can u let us know where and how much roughly u got it for?

Need to check it out!

UG_8

Are you saying the speed delimiter? Our cars can already rev to 9K liow leh

Genesis

Wouldn't you have done the dyno during the install of the unichip to max out the ECU?

CaNNaVaR0

yapz... sorry bout the confusion.. becoz my previous car can only rev till 6 k , so i assume my 8 can go to max of 8 ...

Hi sorry...been busy. Just installed the chip and did some light tuning . Wanted to dyno both the chip together with the exhaust mods, so I took the car back first to use as I had errands to run. Will be doing the full dyno tuning once my exhaust work is done.
You can check out more about the Uni chip at the website below. it costs about $850 including installation and tuning. You can call Max at G-motors 90666807. He is an authorised unichip tuner.

Just did my Dyno yesterday!! Dont have a scanner so can't post the chart yet...gonna borrow a friends one. Anyway here are the figures for those interested. Please note that this dyno includes my exhaust work and is for pre and post unichip.

Pre Unichip Power 211 PS at 7671 rpm
Post Unichip Power 231.3 PS at 7657rpm

Torque Pre : 18.7 kg/m at 6513 rpm
Post : 21.3 kg/m at 6360 rom.

Cheers

Actually, that is very good.

Can you tune the Unichip yourself after the install?

Zo0oM

:D Cool!

What kind of exhaust work did you do?

ethan113

Hehe this is what www.racingbeat.com has to say about exhaust work:

"The following table lists the measured power gains from various aftermarket components. Testing has been conducted on the Racing Beat engine dyno with both pre-production and production Renesis engines.

1. Intake – enlarging the oval inlet to the factory air box - +2 HP (this modification eliminates the VFAD intake duct.) Developmental work is still being undertaken.
2. Headers – approximately 4 HP peak power gain.
3. Mufflers – muffler & connecting pipe - 2-3 HP.
4. Removing the muffler from the car (engine) – about 4 HP.
5. Remove catalytic converter and resonator from the engine completely, and replacing with "cat" replacement tube – max benefit 8 HP – regardless of what muffler is used (or even no muffler)."

No prize for guessing what I did :P

Anyway, the Unichip is tuned by my mechanic who is a trained Unichip tuner. The chip programme he used is a recent release specifically for the RX8. Actually, the manufacturer's claim was only a 10-12 hp increase, so I was really pleasantly surprised with the 20 hp gain. I don't really think you can tune it yourself though.

But if you think about it, the Euro Spec RX8 is detuned to 231 from 250, so essentially I think what the Unichip did was kindof similar to what the M-flash would do??? My Mech wasn't confident about pushing the tuning further, although he said it was possible, but he was afraid of pushing the engine too hard. He will probably try again in future if I'm willing to push it, I guess

sgrenesis

so your car is actually an auto but what would be the gains without the exhaust.

sqflyer

No prize, but I'll take a stab anyway and guess that you let the "cat" out of the bag? If that gives max 8HP as stated by Racing Beat, then maybe the Unichip IS really giving 12HP out of the total 20HP gain. I think $750 is pretty darn good for 12HP (provided it doesn't kill your engine in the process). I know people who have paid a lot more for 12 horses.

Ethan, can you confirm if it's a piggyback mod that can be easily removed?

ethan113

Huh? Nope my car is not an auto. It is the 6 speed MT (euro spec).
The dyno was done for before and after the unichip, the exhaust works was already done as a baseline for graphs. I didn't do a dyno for before and after my exahust mods. According to the dyno, it was about 20 PS gain with the chip.
Will try to scan the charts in and post it tomorrow.
Anyway, sgrenesis, if you have any questions or clarifications, can just pm me, we can discuss more then.

ethan113

Hi hi...sorry just to clarify, like I told Sgrenesis, the dyno was done already with the exhaust mod in place. I did not do a dyno for before and after the exhaust mod. So essentially the dyno I did was before and after the unichip only, both having the exhaust mod in place.
I guess this means that the Unichip helped me to gain the full 20hp? hm cant really believe it too but feel free to pm me, we can meet up or something.
Sorry don't really know much about technicalities, so maybe you can clear up my confusion as well.

Yep it is a piggyback mod, easily removed.

Manwe

The best way to remove the cat is take the whole damn thing out, skin the cat and put back the skin(weld it back in place). LTA inspection is visual and they would not notice unless you let the cat out of the bag yourself. Do not attempt to remove the cat completely unless you wanna pay fine and redo your exhaust for another inspection.

sqflyer

Thanks for answering my queries Ethan... $750 for 20HP is almost a must do mod liao, provided of course that it's safe and doesn't damage the engine.

Manwe bro... so I assume you've already liberated your cat skin? lolz...
Si bey sian... doing a double MEL back to back... can you believe it?!??!

Ringer

Just a guess. Your exhaust mod gain may not have been fully realized in the first place without reprogramming. Hence when you installed UniChip and reprogrammed you got your 20PS gain from both the exhaust and remap working together optimally.

ethan113

Hm yep thats probably it. The Unichip manufacturer did claim a 10-12 hp gain.
Well anyway, the low end has benefited and Im not complaining
Hey Manwe, already did as you said hehe
