Wait, that's a supercharger? Those pictures on the last page show what looks to me like turbochargers... *confused*

My ignorance aside, very nice build.

Very nice build thread and nice car. What other plans do you have for your car?

You could piggyback it. But you'll have alot of CEL

Also you could use the DI only setup and drop the PI then run the HKS Vpro. But your just going full stand alone for no reason and losing alot of built in factory tuning that works well for daily driving.

With the HKS OSC you can fix AFR under light loads and map for the S/C setup with stock ECU. Doing everything and still pass emissions in almost every state.

I passed the NC OBD2 test 2 years back to back using the F-conIS and HKS- OSC setup and never threw a CEL.

If the OP does decide to go HKS F-conIS I have maps he can use that work.

I don't have any for the Vpro unless he drops in a 2JZ-GTE single turbo. LOL......... then I haz maps for that too.

Also your tuner will need the HKS tuner dongle and software. There aren't many HKS" pro tuners" left in the US. But you can buy outside the US and get the equipment yourself.

* The stock fuel limits haven't been hit yet. * I've hit the stock ECU map limit's with my last setup before tuning with the HKS unit. which is @ 6psi.

Ahh I completely forgot about our DI system. Doh

What's is the limit of the factory fuel system?

Based on what I observed on my own car, adding some speculation, I would say duty cycles of the injectors would be nearing 92-95% at 8 psi. Only one way to find out though...data log.

Stock ECU limits 80% duty due to overheating the Injector drivers.

Also at anything above 85% fuel psi drops off.

You can get 90% or better if you batch fire the injectors but not in a Seq setup --->OEM

You know this for fact? Would it be the same for the IS250?

^^^ Kinda,

FACT, the IS300 ecu, Supra ECU both limit to 80% duty. I have no data to provide about the IS350/250 ECU but I do know that the duty cycle's via the HKS FconIS were around 85% once I was tuned at 7psi.

So your number of 92-95% is a great guess. If it does allow for it. Which I doubt because the AFR would stay 11.0 at all levels of boost if it did drive to that limit.

Makes sense. I ran full standalone on both my IS300s so I never cared.

I saw 85% duty cycles when I logged the is350 at 7 psi as well but that was obviously on the stock ecu....hmmm I'll have to dig thru the logs I saved but I didn't guess 92+ % out of thin air. . I wish my damn car was close to being buttoned up! Lol

How did you get factual data that it stops at 80%? I ask this because I was making over 505whp on the factory injectors (550cc) which would be far more than 80% duty cycle.

Food for thought there^. Come to think of it Aristo vvti swap guys ditch the 440cc injectors and drop the 550s in to run off the stock Jdm ecu....which again would be pushing above 80% duty cycle given the HP they are putting out on single turbos.


Stew, how's it running now? We got some freeeeezing temps coming this week!

Turbo is using exhaust gas to turn turbine SC is driven by a belt.

Funny you should say that. I held just over 5psi today and got a quick CEL. Check VSC with the Trac light on. Was there for about 10 seconds, then everything returned to normal. The ECU did not like boost in this cold weather. I'll consider that the only warning I need to take it easy in cold temps.

Speaking of CELs and boost... I need to check if my CEL is still the code thrown from my headers or from running lean being boosted now.

Problem is, some of the Lexus CELs are completely ambiguous. I had the code ran on my girlfriends '01 RX300 when she had a VSC light and it basically said 'Yea, this could be anything that has to do with something around the engine.. or something like that. But probably nothing to do with VSC".
