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.

    • I usually source pressure on inlet manifold after throttle body
    • Where is the best location for boost pressure source when running mac 3port boost solenoid?  my new turbo does not have a fitting for that on the compressor housing.  how come Garrett make a turbo without that?  im confused 
    • From my memory, which isn't that great, we did have issues getting the large throttle body on my old LS1 to play nicely at idle, first it would stall, then it would only idle at 2k rpm, then it would hang at 2k rpm for a few seconds and then drop and stall, then, finally, the best we got was it would hang at 1.5k rpm for a few seconds then drop to around 800 rpm The tuner stated that large cable throttle bodies are a PITA, and if I wanted anything better than what we ended up with I would need a electronic throttle body and all of the aftermarket ECU stuff to run it
    • So, my intake arrived  I'm not happy with the coating finish so I went to Supercheap and got some black wrinkle paint and some prep stuff I was initially thinking about using grey wrinkle paint, but finding a quality product that gives the texture I want was "unfindable...", so the tried and tested black wrinkle paint is again finding its way into the engine bay for the OEM look I'll sneakily head into work and get the big ovens cranking to cure the paint over the next week or so I've also contacted MX5 Mania today to talk about the install and tune, so painting it is my "main effort" prior to sending the car off In other news, the correspondence from the US supplier is fair to midling to say the least, I'm still trying to track down the intake box thingie with the larger intake pipe to suit the throttle body, it still is "awaiting fulfilment" (no stock currently available), if it isn't here soon I'll just get MX5 Mania to fabricate up a CAI that is easy to service the air filter  
    • Thanks mate. I thought it would be that way.
