Wat Boost Controller?

The AVCR is actually a really really good boost controller.

The problem is they are not super easy to setup and this is where a lot of people come across spiking problems.

As with all boost increases it should be setup on a dyno.

I had a blitz sbcid ebc and on the road also found that difficult to setup correct as to prevent spiking it requires a few full rpm rev from just off idle through to redline in fourth gear. So not exactly possible. :S

All self duty cycle learning type boost controllers will have this problem. Get them tuned on a dyno and they are all good.

yeh was close to getting a black avcr but i got a blitz sbc i-d III the guy at auto barn talked me into it lol good 800 spent get it installed sat then i need to take it somewhere to get it tuned ayn recomendations for somewhere up north?

See how you go with it in manual mode; if you are dropping boost at higher revs throw it in auto mode and have it do its boost curve learn thing in 4th gear.

The one issue with auto mode is its prone to spiking IF you don't load it up enough from a low rpm i.e 4th gear.

The spiking will occur when you put your foot down and hold it up a steep hill at lowish revs.

Dropping boost depends on the boost your running vs what the actuator is rated at, how good your exhaust is and if the turbo is nearing its flow limits.

Manual mode offers the best boost response. If you have a keen seat of the pants feel you will notice the manual mode has much sharper response. THe issue with manual mode is your not able to dial in more duty cycle at higher rev's; its a fixed value.

Auto mode alters the duty cycle through its learning. :)

I prefer the AVCR due to its fandangled features; which really are not needed unless your making a good whack of power i.e different boost levels for each gear.

I've got the Blitz SBS ID III also, I've had no spiking issues what so ever. Just for a start try using auto mode duty of 30 and whatever psi you want to run, don't over do it!! i teach mine by doing a 2,3,4 gear run. once the L disappears from the top of the screen record the same type run and check for spiking on the boost graph. If there is none up the duty 5 or so and repeat untill you get a little spiking and then back it back off. I think mine ended up being around 50 duty.

If you're after even better boost response you can use the scramble function and set a manual level for the first few seconds and then switch to the auto mode to prevent drop off at high rpm.

When you're using manual mode the instructions say not to go over 15duty with an actuator type wastegate.

There is a good tread by Col-gtsx but that was a long time ago, do a search for it and also for english instructions as there are some around somewhere, maybe try the Blitz site also.

Also, for your next purchase try www.nengun.com

Will be handy when you ramp up the boost. :)

Mines close to being finished, it will be very interesting to see how peak power differs.

Your running on regular 98 pulp? std cams?

Yeh runnin bp ultimate, and will have tomei poncams in then 256 deg aswell as splitfires so should be very interesting

I use the Blitz DSBC Spec-R and have had no problems with it. Works great and super easy to set up, only two things to set. :)

Have another dyno sheet of it holding 20psi the same, but havn't got it scanned.

It doesn't have anywhere near the features of the ACVR or the SBC-iDIII though, sometimes I wish it did have those other things, but it's pretty rare that I do. All I ask of the controller is that it keeps the wastegate closed for as long as possible and holds boost steadily. This one does that, and it cost me $300 2nd hand :)

      Welp, good to know. Will have to wait awhile until steady hands with drills and taps are available. In other news, these just arrived! I will weigh them for posterity.

      100% the factory sender is tapered, that is how it seals (well, that and teflon paste or tape)

      Thanks folks - I've saved a few links and I'll have to think of potential cable/adapters/buying fittings. First step will be seeing if I can turn the curren abortion of a port into something usable, then get all BSPT'y on it. I did attempt to look at the OEM sender male end to see if it IS tapered because as mentioned you should be able to tell by looking at it... well, I don't know if I can. If I had to guess it looks like *maybe* 0.25 of a mm skinnier at the bottom of the thread compared to where the thread starts. So if it is tapered it's pretty slight - Or all the examples of BSPT vs BSPP are exaggerated for effect in their taper size.

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
