SKI Posted April 27, 2004 Share Posted April 27, 2004 I've just bought the EVC5, (had an AVCR but after reading so many bad threads about it, I so sold it before even fitting). Anyone had any, or know of any problems with the EVC unit, a few people thought that they dropped boost occasionally. It seems to popular in America, would be really interested to hear what anyone has to say/advice/warning/praise even! SKI Link to comment Share on other sites More sharing options...
SKI Posted April 29, 2004 Author Share Posted April 29, 2004 OK so noone out there that's fitted one of these things, some people love them others say that the thing screws up cos' it can't cope woth the TT sequential turbo operation. Anyone have an opinion on this before I decide to fit or sell mine. Must be someone out there who has one... Link to comment Share on other sites More sharing options...
SKI Posted April 29, 2004 Author Share Posted April 29, 2004 Lots of spelling mistakes above representing my frustration with this device..... Link to comment Share on other sites More sharing options...
Nic Posted April 29, 2004 Share Posted April 29, 2004 I've had one fitted for about a year now and it works fine, although I have my turbos set up to run in parallel, so not sure how it will cope with the sequential set up. Link to comment Share on other sites More sharing options...
SKI Posted April 29, 2004 Author Share Posted April 29, 2004 Thanks for the advice Nic, There must be someone on the forum who has ran the EVC5 in sequential mode on a Supra... Just out of curiosity where did you mount the display and the gain controls!? Thanks Link to comment Share on other sites More sharing options...
fisherjohn Posted April 29, 2004 Share Posted April 29, 2004 Have had mine fitted for approx 18 months. Never really used until last weekend when we managed to get the car running ok after many problems. We ran car up from second turbo coming in at approx 15 psi and then gradually dialling in the gain until we stopped at approx 21 psi - it was working fine and still is and obviously my turbos are sequential hybrids.

Interesting, were any of the problems you experienced related to the EVC5, or just other issues!? Since you've calibrated it John have you had any incidents were it mysteriously drops boost, there was concern that the fuzzy Logic/Self learning features of the device couldn't really accomodate the sequential setup, which confuses the unit. It's good to hear that you have got the thing running, I'm still in two minds whether to have mine fitted or go for something else that is better documented.

Nic Posted April 30, 2004 Share Posted April 30, 2004 I have the display mounted where the clock is, i.e. coving the clock, on the LHS of the dash just below the warning lights. The controller I have recessed into the dash under the stereo where the buttons for the front spoiler use to be. Link to comment Share on other sites More sharing options...
SKI Posted April 30, 2004 Author Share Posted April 30, 2004 I've spoken to a couple of the popular traders on the forum who have been very helpful to say the least (so top marks there, especially Gaz at Envy), the gerneral opinion seems to be that if it's plumbed in properly it should be OK. Would still be interested to hear from anyone who has had good/bad experiences with the unit, especially your setup values, that would really help point me in the right direction.

SKI Posted June 16, 2004 Author Share Posted June 16, 2004 Was dissuaded by CW, went for bleed valve option and have to say more than happy, now that the setup is perfected the car runs superbly Car has stable boost at about 1.15 bar, my boost control is now my right foot SKI Link to comment Share on other sites More sharing options...

Aha! This assumes you know how to program it then. I have no instructions and want to fiddle with mine, but I need to know all the right button combinations etc to muck with. any chance you could scan and email the instructions? Or perhaps write a better set as I hear they aren't perfect? Any help would be hot, I don't want to have to belt around in thrid gear in "learning mode" - I know what settings I want. thanks!

Wez Posted November 19, 2004 Share Posted November 19, 2004 The HKS EVC boost controllers use fuzzy logic which when used with sequential turbo setups should be disabled, you use to be able to do this on the EVC 4 with a switch on the back if I remember correctly. With this turned off it is then manual setup and should not be an issue. Link to comment Share on other sites More sharing options...

That's cool but I still need the instructions on how to do it and manually program the unit - I have no documentation at all for the V series. SOMEONE must have a manual or something!

chris_bramley Posted November 19, 2004 Share Posted November 19, 2004 FYI y'all, this was HKS's FORMAL word on the subject: "...contact the HKS dealer that originally purchased the unit from. They will be able to supply you with replacement instructions." I said I couldn't (came on the car)... "...due to the nature of the product and the ramifications of getting it wrong I would contact a HKS dealer and have them set the system up for you." Jeez, I just want the MANUAL! If I wanted it retuned I'd ask, but since I'm a computer engineer and capable of far more complicated things than a 4 button programming control I am almost POSITIVE I can figure out safe running parameters. All I need is the manual to say how to set it, and I'll go from there Link to comment Share on other sites More sharing options...
Lucifer Posted December 1, 2004 Share Posted December 1, 2004 I have all the instructions for the HKS EVC5, I have fitted this to 3 TT's now jpec and all have been setup by myself. I can offer an installation service for this product if you like on a saturday in Bristol. I have mine setup for 1.0 Low and 1.2 High works great with Sequential, tested fine for transisions too... I am a private person and am not a dealer of any kind. Cheers. Link to comment Share on other sites More sharing options...

Guest Usmann A Posted December 2, 2004 Share Posted December 2, 2004 The switch at the back of the Unit, is a "Poppet vs Wastegate" Poppet =internal gates(stock supra) Wastegate=external units. I am not 100% on this, will check now. Link to comment Share on other sites More sharing options...
