HKS EVC IV boost controller help!!

[Guest craigynett]

Hi

 

i'll start off by saying a big hello as i'm new on here

 

I don't actually own a Supra, have thought about it in the past tho & may do in the future. At the mo I have a 99T Evo V.

 

Basically i'm wanting to lower the high boost setting on my HKS EVC IV. Now i've tried both UK Evo forums & a couple of other non Evo forums but nobody has replied on any of them:search:

 

High boost is set at 1.25bar. I wan to lower it to 1.2bar. I've got pdf manual for the EVC IV but all it only tells you how to set it up from scratch

 

Thanks

If I had set mine up I could have gave you some help, but I aint so not helping am I:rolleyes:

 

There is software available for it now from sumo power for about 90quid I think, that would be easy configurable

 

if its anything like the evc3 I used to have then you had to hold the select button in for over 3secs to enable it to edit mode then you lower it with the up and down buttons, holding down the slect button again to come out of edit mode, dont forget it will only open the wastegate at this point, it wont stop your car from overboosting above 1.2 bar, if you have a 3inch exhaust you will need a restrictor ring to limit the boost, if you have a 2.5inch exhaust you should be fine,

 

once you have set it up, take it back to the dealership and buy a real jap car;)

You must have read my mind, I've always fancied a Yaris;)

 

As for the boost controller. Somebody off another forum sent me a link. I've printed off instructions & have just lowered high boost to 1.2bar. Took it out for a steady drive heading towards a nice long road i know that's usually quiet at this time of the eve where i could test it.

 

Revs went all the way to 7k rpm & not a single cough or splutter:) I'm happy as Larry now:d Altho i don't personally know Larry so i couldn't actually say how happy that is:sly:

 

Really i think i need to get some £ together so i can get an Ecutek remap. Just need to get a couple weekends of O/T in at work, shame we're really quiet:( I'll just have to rent my Mrs out:eyebrows:
