Blitz Boost Controller Basics

[@brianheiden6623]

Nice looking controller, seems to have a lot of functionality as well.

[@Gabe_Fe]

Hey Seb. Is this controller worth using in 2024? Or should I switch to the recent Greddy profec

[@specialtyz]

If you're looking to purchase a new controller go with the Greddy Profec. It is by far the easiest, nicest, and most cost effective controller out there. These old Blitz units are no longer made but if you have one in your possession it is still a great controller. I still have one in one of my Z32s that is still functioning.

[@Gabe_Fe]

@@specialtyz thank you!

[@darrencooper7282]

Its funny. I went to look for a video on how to use the blitz boost controller. And the first video i find is specialityz. Im pretty sure they built my z32tt that im trying to learn how to use LOL. What would you recommend my settings to be at? I have it on flex fuel about e34 at the moment. Also have blitz power meter im in new mexico so elevation sucks.

[@specialtyz]

The settings will depend on your setup, however I would recommend starting at 30% and going up from there. On an E30 mix you can probably get away with 17-18 psi of boost.

[@justinr2911]

do you have a video or thread for actually settiing one up mines single

[@specialtyz]

+Justin Roberts Settings or installation? Single solenoid would be the same settings.

[@justinr2911]

Settings. I have set it to 14psi with 25 fain but onoy runs at 8.1 actuator pressure and wont go higher

[@specialtyz]

+Justin Roberts You need to ditch the auto setting. Use manual mode. Start at 30% set.

[@steveromeocars]

Have you got a video, where you show the installation? One Silicone hose from the solenoid goes into the wastegate, and the other? On the nipple which is on an intercooler tube? Have a RB25det.

[@specialtyz]

The IN port comes from the signal which ideally is before the throttle body and after the intercooler. The OUT port will go to the wastegate(s).

[@steveromeocars]

Thx Dude, I already managed it :) Now the other problem is, that the boost will only be at 0,8bar on 5000rpm. Gain is for boostcontrolls, but how can I get maxximum boost on 3000rpm? What shoul I do with set?

[@specialtyz]

What's it like the rest of the RPM range? Max boost will greatly depend on the size of the engine\turbos. If you have a big setup the further up the RPMs MAX boost will occur.

[@steveromeocars]

No its Original Setup. I just want maxx Boost(0,8 Bar) on low RPM... So its the "Set" (Duty Cycle) That I have to adjust higher????

[@SPIRITjpDriftingSeries]

@@steveromeocars adjust the gain setting to increase spool. Changing the gain setting will also affect total boost level, so make sure to adjust duty cycle (and keep an eye on it) when changing the gain setting.

[@jp.notfit]

I have the same blitz boost controller for a stock nissan skyline r33 gtst currently in japan and running on 93 octane what would be the best setup? Supposedly 12psi is the max I would want to do with a stock turbo and I left my controller at channel 1 with 30 would you have any recommendations? Sadly everything in the manual is in Japanese and I can’t read it lol

[@shirok4140]

Lucky. Id like to see your skyline. How much did you get it for?

[@jp.notfit]

Shiro K Bought my skyline for 7k back in April of this year

[@specialtyz]

30 for the set is a good starting point. Use 10 for the gain setting. Make sure to use at least 3rd gear to check boost levels.

[@jp.notfit]

Sebastian Chacoff sweet I’ll go ahead and test that out then thank you for the help !

[@Darksaige]

I came here for the same reason. So after getting a bassline on how it works I now want to play with mine and see what it does on my R33

[@abdulbasir1100]

Sebastian what if the car is twin turbo stock and I set it to auto?

[@specialtyz]

Won’t work unfortunately. At least not on these specific units.

[@zxline]

What factors determine the Gain setting? I.E a setting of 10 vs 15. Is it elevation, Octane, Mods?

[@specialtyz]

Most of it comes down to the turbo (sizing), wastegate spring pressure, and how the response is. Over 90% of the time 10 is usually the best all around setting for most applications.

[@ariesanfilippo1078]

Mine was working good and turns on. But It’s not showing any boost or even moving. It stays stuck. What can cause this.

[@specialtyz]

This could be the actual "brain & sensor" for the controller, where the boost line goes to.

[@ariesanfilippo1078]

@@specialtyz where would that be located? I didn’t install it. Came with the car when I imported from Japan.

[@specialtyz]

Hard to know as installation is unique. You would want to start by following a vacuum line that goes into the cabin and also the wiring from the head unit to the "brain".@@ariesanfilippo1078

[@tomar646]

Hey nice video got the same controller, and I need help with setting up can you shoot me a message and help me with that a bit I am rebuilding my z i got it from auction was flooded I rebuild preety much everything but I'm coming from supercharged cars and still learning about turbos let me know thank you

[@rice114]

single or dual solenoid?

[@specialtyz]

+rice114 This one is dual.

[@samkendall5276]

Is dual only used in twin turbos?

[@23darrencooper]

Dam this controller is way more complicated than my profec b was. I just want to set it to 23psi and 15psi 😩

[@Russpeed301]

It's a Zee!

[@MINESINCLINED]

How much duty cycle is 17psi? I kept thinking that duty cycle number= boost psi

[@specialtyz]

Varies with turbo size and base WG setting.

[@MINESINCLINED]

Sebastian Chacoff oh okay! I set it to 30 and did a decent pull and peaked at 13.3 psi I'll do some more pulls and adjust accordingly. Thank you

[@justinr2911]

ok cool i have set mine to 14psi with 25 gain but only goes to 8.1psi

[@shirok4140]

Same here. Got the same problem lol
