I was going to chuck a scope on the factory knock sensors. If anyone has any suggestions in this area please let me know. Cheers Matt.

I have access to a new dyno install, a dynopac 2 hub setup. It hasn't been fully comissioned yet so there is no tuning gear yet, just the dyno so I need a wideband - free dyno time so it's offset a bit. Thanks. Matt.

I appreciate all the responses here but I wish people would stop saying that an aftermarket ECU with bigger injectors is the best way to go. Clearly a new ECU install and tune is the most optimal way to go but you are looking at at least 3k NZ for a semi reasonable ECU, installation and tuning...

That seems like a massive amount of pressure!! Without sounding like a newb... with an M90, I assume one side has vacuum and the other has boost. Before the charger is vacuum and after is boost? When connecting a rising rate reg or a boost gauge I assume that I need to plumb into the...

Steve when you say 12:1, does that add 12 psi of fuel pressure for 1 psi of boost? If stock pressure is 40psi and boost is 6 psi then is total pressure 72psi or 112psi? Surely not 112! Cheers Matt.

Thanks man. Can you tell what ratio it's using for enrichment or is it an adjust as you go type of setup? Cheers Matt.

spf_lexus - the thumb adjuster, is that for the rising rate component? Have you got any pics of yours installed? Cheers Matt.

Thanks for all the info guys. How are the adjustable units adjusted? Threaded rod? What ratio's are people running? Matt.

Cheers. Which model did you get ? They list a few vehicle specific ones. Did you just use a barb fitting to insert into the return? What ratio are you using on it for enrichment? Cheers matt.

How did the unit fit up in the end? Was it bolt on? How is it adjustable? Cheers Matt.

Thanks Justen. I don't know if anyone has actually done a dyno run and checked AFR's with some boost. From the readings I have done there is a lot of fat in the stock fuel curve, perhaps there is not enough. Anyone have a brand of RR reg and any settings that can be shared? Cheers Matt.

The key here is that I am not doing any other fuel management, stock ecu, stock injetors, stock pump. I understand that a RR reg might not be perfect but I am not looking for perfection, just whether it's needed a it's one of a few limited options. Cheers Matt.

Thanks Steve. So running the RR reg after the stock reg will increase the pressure in the rail through the stock reg which still thinks it's at whatever specific pressure. Is your RR reg adjustable? Have you dyno'd and run a wideband sensor? Cheers Matt.

Nice work Cribbj. Wll be an amazing motor when it's finished. Matt.

Thanks for the replies. Stevechumo, how do you run your setup? You mention you keep the stock regulator but still use a rising rate regulator? The way I understand it is that just increasing the base pressure will richen the mixture up across the board by effectively increasing the amount of...

Thanks Justin. I thought the stock regulator was only vacuum referenced - I thought there was a difference between vacuum and boost aware units? Cheers Matt.

I am nearly finished acumulating all the bits and pieces that I need to get an M90 on my 1UZ Soarer. The plan is to run 6psi on stock fuelling and ECU. I have access to a dyno and will be installing an Innovate wideband sensor and gauge for when I do the first power run. Depending on who you...

Wicked conversion. Matt.

What are your caster and camber specs? I am about to go for a wheel alignment soon will post my specs for comparison. Matt.

Awesome work mate. You will be looking forward to the startup. Matt.
