If you go into advanced settings for the boost cut you can narrow down the threshold which the cut activates

This is a very nice and creative build from a customer.
Recipe:
2 pc Vi-PEC V44 (old Link Storm)
1 Celica,
1 MR2,
2 pc engines,
2 pc gearboxes,
1 big Precision turbo,
a lot of cutting and welding.
A lot of thinking
More fabricating,
Etc,
Car is absolute brutal! Enjoy:)

 
 


 

 
 
 

 
Tuning with 2 laptops. Btw a pita to tune:)


 

 

Hi people,
 
I've got a weekend/track car that I'm setting up a link G4+ on.
It runs a 2l NA engine with Variable valve timing, 6 speed box and some other fun bits.

Thought I'd put up a few posts here as a log of experiments / successes / failures with tinkering and tuning with the G4+ Xtreme.

 
 
The motor that I am using is a Redtop 3SGE engine from a 1998 SW20 MR2. It's basically a less common variant of the Altezza engine, has 11:1 compression and makes 200hp as standard.
Thankfully after a basic wire up, the base tune for the Altezza in PClink gave me a really good head start for getting up and running.
It was great having all of the VVTI pids etc all worked out and coilpacks etc firing up first pop. Really impressed!
One thing that I needed to do though, was figure out the optimal cam timing for the VVT cam on the inlet (exhaust cam is fixed on these motors)
I still had the MAF sensor in place, in a datalogging function. I figure whatever cam setting shows the highest volume of air coming through at full throttle, must be optimal.
So I ran datalogged a few rpm pulls with the cam timing statically set to 0, 10, 20, 30, 40 degrees advance.
Then I pulled the data out and put it into a graph.
\
Then so where ever the line was the highest for that RPM, that was the settings I put in for the VVTI map. You can easily see the big advantage of VVTI compared to a static inlet cam.

I compared this to some friends with similar engines who'd dyno tuned, and found the results were very close. The only difference was my bump at the ~4750 mark, but this might be a product of my particular intake/exhaust arrangement.
For the lower load sections I used some guesstimating and some documentation from Toyota. However will keep working on that part some more.

 
 

Hi all,
these will be available also in the next few weeks.
Will work with LINK and ViPEC products
I forgot to mention the unit also has a spare analogue volt input so for example you cold add another temp sensor or connect a wideband AFR signal into it and have that also transmitted via CAN BUS to your ecu etc.
Regards
Dave.

I've written a guide on how I set up the logging to make more useful logs for my uses, track mostly but works on the road too.
