Anyone know what i should set it to?

 

I have a SE chip i think, and cant make much sense of the manual!

sorry that was not very clear was it?

 

Right, i've fitted the unit apart from the pipe work to/from the boost control valve, how do i fit that? i.e. what pipe goes where etc?

 

now i've set up the car setings etc, so the unit reads out speed, rpms, boost etc, and want to set up a higher then stock boost, how do i do that? what do i put for the boost setting and duty settings?

 

also if i do i sensor test the voltage from the boost sender and TPS are not stable, thay move about slightly with the engine not running, is this normal? and the rpm readout whne it is running is unstable too it jumps up and down, even tho the dash rev counter thays at the same position is this right too or have i got a loose connection somewhere?

 

oh, and i have a SE chip, so i can run a higher boost, but still have stock turbos and injectors, and its also a 1992 jap import auto 2+2.

 

YThanks people

Here you go.....

In answer to your other questions, it is normal for the rpm reading to fluctuate and providing your TP reading is 0% when the engine isn't running I would ignore the voltage test reading. TPS voltage reading should be between 0.40v-0.44v at idle when the car is running.

 

As for boost settings, you should consider 1bar (14.6psi) as the maximum although I don't know what condition your turbo's are in and you would also need intake and exhaust with this setting.

 

When setting your boost pressure you will need a good aftermarket gauge.

 

.......if you want 1bar and you boost to only 6psi with the controller switched 'off' then set the duty to 40% and see what boost pressure you get. If you don't acheive the required boost setting or exceed it then increase/decrease the duty setting as necessary. Once you have input the right duty for the target boost.....the unit should self learn.

 

Hope this helps

Just to add to Steve's post, I (and many others) have found the self learn mode doesn't work with a twin turbo. It ends up overboosting. Best to set some values for the duty cycle in yourself (40% is a good place to start) and use the 30 second record/playback to see if boost is spiking or dropping, you can then make compensation by changing the duty cycle at various RPM levels.

 

Did you get a manual with it?? It's quite informative once you get over the pigeon English.

 

Anyone else on here using one of these with a manual box and able to tell me what duty cycle is giving you 1 bar?? Since my gearbox conversion I've gone from under 40% to almost 70% to get 1 bar - just wondering if I've got a pipe off somewhere or the EGR valve is b*ggered...

right, got boost set to 0.80 mmHg and Duty set to 45% and am getting a boost reading of 0.65mmHg is this right??

ummm...not quite.

 

Here's how it appears to work (to me)

 

You set the max amount of boost you'll reach by altering the duty cycle. The boost setting is like a guide - if you are using self learn mode and the duty cycle is auto learning (setting reads '***' meaning duty cycle is different for different rpm and the AVC-R will adjust it to give you the boost you set) then you can alter the boost setting and ignore the duty cycle. BUT as previous post - twin turbos are known to be problematic at best with self learning mode so you're really best off controlling it by adjusting the duty cycle and checking the readout. If it's too low, increase the duty cycle and try again, too high - drop the duty cycle.

 

You can disable self learning in the 'etc' menu. LMK if you need help with this.

 

Presumably you've set all the car settings up correctly in the 'etc' menu - car select etc...? Also you've disconnected the stock wastegate solenoids?

 

HTH!

 

PS don't worry about the fluctuating readings - that's digital technology for you!

Right now been for a bit of spireted driveing, had the controler set to 1.00 bar and a duty cycle of 65% and got a peak reading of 0.88 dose this sound right?? i'm new to this so am haveing a few probs setting it up right!

 

oh, and it does not go into self learning mode!!

Hi, you can ignore the boost setting and just concentrate on the duty cycle if you're not trying to use self learn. It takes a couple of runs with your foot down to get into self learning mode - if it's not going into self learn mode then it may already be disabled which is probably best IMHO.

 

My duty cycle is set to 65% - 70% depending on rpm. I didn't want to suggest such a high setting as I thought I may have a leak somewhere hence you'd blow the top off an airtight engine ;) You should use the peak hold facility to check what the actual max boost was rather than trying to watch while you're flat out...best just to monitor the boost and rpm (2 channel)

Thanks m8, i've got it to read 1.00 bar now, needed a duty cycle of about 65- 68% and its now gone into learning mode!
