Hi Ashley - Yes, I'm very familiar with PCLink, but I feel really designed for tuning the link with most of the display dedicated to the fuel and spark grids. What I'm looking for is a program dedicated to a "Dashboard" where the whole screen would have nice gauges for every aspect of the LinkPlus. I know you can reconfigure PCLink to show any values on any of its preconfigured gauges (as well as the min, max and warning levels) but I guess I want more. Would LinkElectro consider making a driver available to allow development of our own custom "dashboards" with just a read only view of the outputs from the ECU? I would not want to be able to set/store any values, just have read only access. I keep picturing some of the displays that you see on the LCD dashboards in Fast & Furious. PCLink is not at that level. Paul...

Hi Ashley - Just wanted to check in again to see if anyone else was there to ask about the intercooler control. Your heat soak issue makes a lot of sense. Having the intercooler stay hot from the last boost would not be a good think. If the fan was controlled by MAP, and MAP dropped below 100 KPA, I would think the air flowing inside the intercooler would be close to the ambient air temp (no pressure, no change in temperature?). Would this then cool the intercooler back down pretty quickly by just using the air flowing through the inside of the intercooler? I wonder if I could use a relay with a capacitor and resistor set up to latch the fan on for a number of seconds after the boost drops off. This way the fan would stay on say for a minimum of 10 seconds after boost disappears thus allowing the left over heat to be removed from the intercooler. Seems like it would be simple enough to wire up and using a variable resistor, I could adjust the hold time when the LinkPlus shuts off the Fan-On signal. Thanks, Paul..

My new set up has a fan on the intercooler. After reviewing the (old) LinkPlus manual, it looks like I could control this through the Drive A, the Drive B or the Water Spray outputs with a relay between the fan and the output. Drive A and B can switch based on RPM or %FF while Spray can be based on %FF or MAP. I would assume Map over 100 KPa (or some KPa over 100) would be the simplest setting so the fan is fully on as boost rises while its off under any vacuum. Is there a preferred output and configuration to control an intercooler fan? Paul.... PS. My new Bosch IAT sensor (part # recommended on this forum) read perfectly when I hooked it up last night. I hope to get a chance to do a test drive tonight...

I love the idea you have put forth with the DisplayLink, but I'd like to run the DisplayLink software on my laptop or better yet a computer built into my car with a dash mount LCD screen. Would you make the software (or a driver so I can make my own software) available to get a read only view of what the (old) LinkPlus supplies on the serial output connector? I've considered using the DOS based logging program you provide, but the DisplayLink is very close to what I'm looking for. I'd like to be able to add a Speedometer based on the RPM and overall drive ratio - probably displaying 4 possible speeds - one for each gear I may be in. Paul...

Thanks, Ashley - you've confirmed that there isn't a good solution except a blow off valve. I'll keep the boost down until I can install one. Is there a preference for the source of the boost pressure to run into the EBT - just outside the turbo outlet or from inside the manifold after the throttle body? Thanks! Paul...

Let me clarify my concern... If the EBC pressure source is the intake manifold after the throttle body, I'm worried the following sequence will occur: 1. at 15 lbs of boost, the throttle is slammed shut 2. The LinkPlus sees MAP vacuum and stops cycling the boost controller 3. The waste gate closes 4. The engine continues to spin, causing the turbo to build a lot of pressure between the turbo and the throttle body. 5. The throttle body butterfly bends under the pressure... Paul...

I've just installed a larger turbo on my EJ20 and am worried that running the electric boost control feed from inside the intake (after the throttle body) will not allow the waste gate to open while under boost if I take my foot off the gas. I currently have a hose directly from the turbo outlet to the waste gate to run off the default 5lb spring, but want to reincorporate the EBC as soon as possible. What should I use for the source of the boost control? Pressure before or after the throttle body? Does it make a difference because as soon the LinkPlus sees vacuum from the MAP tied in after the throttle body it would stop cycling the EBC, right? Is it safer to just add a by-pass/blow off valve before the throttle body? Paul...

My EJ20TT came with the following idle control: 22650AA131 A33-606R16 Unisia JECS. This unit has: 3 wire connectors  2 screws that can be loosened to allow manual rotation of the entire IAC A hose barb fitting A one way valve on the engine side The center connector appeared to be a ground, supplying voltage to one side decreased idle and the other side increased idle - if I remember correctly - I could have the ground/voltage flipped. Air flow control seems to be done by rotation of a "vane" inside the unit. After hooking the LinkPlus idle control to the high idle side and the center connector to ground, I could not get the LinkPlus to have any control over the idle of the engine. Can the LinkPlus control this type of IAC? Should it be set up as a stepper motor instead of pulse-width-modulation? If the LinkPlus can't control this, I'd like to put a pulse-width-modulation solenoid between the hose barb and the air cleaner, crank up the Unisia IAC to high idle by rotating it and use the secondary solenoid to actually control the idle. Any recommendations on a standard part for this purpose? Thanks, Paul...
