I had a Toshi chip put in & it made decent difference between 3800-7000. Felt stronger & more responsive. It was $250 for the chip fitted to your ECU or $350 to by a chipped ECU outright. What you get out of it depends on what mods you have to an extent. Mine's just got an RB25 turbo, 3in turbo back exhaust, filter & R33 GTR fuel pump.

Can anyone recomend a good place in Sydney that can do a rom tune on a RB20?

Im also keen to get some tuning done. Not that i dont trust toshi, and ive read the reviews in his posts many times but it just worries me that he doesnt do any tuning on the dyno or road...... I know you have to inform him of mods you've made to your car but each mods will change depending on the health of the individual engine and what products you use etc...

also i take it that toshi takes of the speed and boost limiter??? does anyone know what the factory boost limit is????

confused.

:D

Toshi will make a chip based on the info you give him. Then he hooks up his laptop & a Lambda sensor to your car for a road test. Checks boost/AFR/ingnition maps you have. Then he'll demonstate the chip he's made by putting his ECU with your modded chip in and doing the same test.

With the chipped ECU he can then use the laptop as per a fully programmable ECU to adjust ignition & fuel maps until you are happy with it. He can then make a new chip to suit if required. It took a couple hours all up for me.

He has all the equipment to perform this on the road but I'm sure if you wanted to book some dyno time instead he'd be happy to. & yes speed & boost cuts are removed.

Best to talk to him about it on yuna at tpg.com.au

He is japanese so his english can take some getting used to on email/phone though... :D

Thanks for clearing that up!!!!

when i get my front mount its on!!!!!

I haven't had it dynoed since but he seemed to think it had similar 'seat of the pants' feel to 170rwkw R32's he'd been in. Not much really but my car is pretty long in the tooth both in km's & years so thats fine by me.

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
