October 17, 200421 yr Welcome to tonight's program! Tonight will be the 98521980475347.4333 th episode of WJM and the infamous GL-10 racer wagon! Tonight we will be installing a GReddy PRfec B-Spec II electronic boost controler. After that, WJM has found a NAPA/ECHLIN IC12 ignition coil amongst all the SUBARU stuff he has, and will be installing it inplace of a 2 year old Accell super stock coil. After those two items are installed, a test drive will surely commence! *now if I can just find my wire strippers, I can wire up power to the PRofec and then install the coil... * Stay tuned!

Be sure to inform us on how to install this device. I think I'd like to have something cool like that. Of course I won't use it yet though. *cough*
October 17, 200421 yr *now if I can just find my wire strippers, I can wire up power to the PRofec and then install the coil... * Stay tuned! Being an electrician by trade...I will give ya a little hint..when u cant find your strippers...use a lighter:grin: Have fun!!
October 17, 200421 yr or I just cheat and use the dikes that I cut with to strip them or use a knife (and that is the "be careful with what your doing with that knife safety warning")
October 17, 200421 yr Author Found the strippers....but now ive got a problem with previous owner+solder+solder all in the connector=connector doesnt slide in and make contact. Now ive got to correct that.
October 17, 200421 yr The previous owners hatchet job wiring is the only beef i have with my car. They took out connectors and did the old wire twist with low quality tape thing. This coil what kind is it? What kind of difference are you expecting other than not haveing the accell's limitations? I want to trash my accell.
October 18, 200421 yr Author More details when back from the test drive. swapped coils. made makeshift wiring connector that looks like it will be peminant...if not...easy fix sstill...EBC is easy to remove from the stop its in...easily accelsible, seeable and tunabel going down the road..eventho manual say NOT to do this...hahaha More details when back from test drive. Oh, note: WIth the IC12 in, NO miss at idle anymore....we will see after a drive tho.
October 18, 200421 yr Author Myxalplyx: Install was stright forward...instructions in Jap and Eng! Comes with the EBC module...can put it anywhere pretty much...some vac line, harness for both the boost control solenoid and power for the EBC brainbox. Power: Just black wire to ground, and the red to an ignition switched fused power source. Done! Vac line for brain: tee'd it in with the boost guage...reads vac and boost right off the manifold. Boost control solenoid: Has line in for presure...and line in for wastegate, do not mix this up. Pretty stright forward tho. (note: I did use the turbo compressor housing as the boost source, may change this later, just for the heck of seeing what happens.) I already had lines routed inside the cockpit from a MBC i had...so I simply put the BCS under the dash near the ECU with those lines....I WILL change this later, as the BCS makes funny noises when controlling boost...hehe...but its a little annoying when trying to hear the engine. The BCS has a nice and tidy wiring harness for it...plug the appropriate end int the brain box, and the other into the wiring connector on the BCS. Done! So...power, BCS, adn vac line. Done! Now mount the thing. Its got really stright forward instrictions on how ot set low and high boost, warning, peak, spike, consistancy, boost cut off (IE, if boost gets too high it will save you!) with on/off modes, read REAL time pressure from the source and is very user freindly and adjustable on the fly. End conclusion: It works, and works well. Well worth the $/time spent on it. Now, for the coil.... Accel Super Stock coil, used for 2 years....replaced with an unknown age NAPA/ECHLIN IC12 Coil (this coil is what NAPA listings show for stock replacement on turbo cars...IC88 is for NA i believe, and NO, this is not the "milage plus" aka mileage less coil that ends in "SB", IE: IC12SB...no, its the good one, IC12). Conclusions: On LO boost (stock) I can ride it all the way to 6200 and everything is smooth as butter...I could not before...i would get missing and all kinds of crap past 5600 or so. On HI boost...i still get the same stuff above 5000....but I can actually feel the knocksensor/ECU/disty doing its PROPER job in retarding the timing due to the high boost conditions...but its retarding it TOO much, and keeping it retarded in the next gear...and bringing it back too slowly in the next gear when I want power...so...EDIS or something to fix that. All in all, the unknown age/unkown useage IC12 is better than the accell. Now back to our regularly scheduled programming....
October 18, 200421 yr Author what are you going to do with the other boost controler? EEEETTTSSS JUNK! IM'in you now.

Some questions: How much boost are you running in 'high boost' conditions?
October 18, 200421 yr Please educate me. What is a boost controller? Is it a stock item? Would I have one in my 88GL turbo wagon? What advantage does one get by installing the one described by the original poster? -Brett
October 18, 200421 yr Please educate me. What is a boost controller?Is it a stock item? Would I have one in my 88GL turbo wagon? What advantage does one get by installing the one described by the original poster? -Brett A boost controller is a device that is used to control how much boost pressure your turbo will make in the intake manifold. There are manual boost controllers and there are electronic boost controllers. A boost controller does not come stock on your car so you will not have one on your 88GL turbo wagon. Will has a "GReddy Profec B-Spec II electronic boost controller". The info I'm about to post is from a Sport Compact Car article I remember reading about boost controllers in a comparison test. Here's some info on the Greddy Profec B-------> "PRofec stands for Pressure Offensive Controller. What that means we're not really sure, and we don't care. The PRofec-B is really good. GReddy's "basic" model features a dual solenoid design similar to the Blitz SBC i-D. The solenoid assembly is somewhat bulky, but mounts easily enough in the engine compartment. An additional pressure signal must be brought to the back of the control unit in the cabin. Our tester came housed in a translucent blue case, which lets you see all the electronic bits inside. When lit up at night, it looks like a cross between a UFO and a holiday ornament. Basic black is available for a few bucks more. Where the PRofec-A must be trained in the ways of your turbo, the B model comes out of the box smart. GReddy specifically recommends this unit for sequential cars and problem cases. Straight-away boost is responsive, though further tuning can be made with the balance dial. High and low boost each get their own dial, all of which normally sit flush, and pop out for adjustment. Toggling between high and low boost is accomplished either by the mode button on the control unit, or through the use of GReddy's optional wireless remote switching system. Mount it on your steering wheel, shifter, key chain or girlfriend. Controller: GReddy PRofec-B Pro: Super simple, works great. Con: Sensitive knobs. Cost: $420 in black, $399 in blue, remote switch: $128. Source: GReddy Performance Products Inc. (949) 588-8300 www.greddy.com Aesthetics: Looks like a Xmas tree ornament. Ease of installation: Yes. Clarity of instructions: Fine. Available on Web site. Features: High, low boost, adjustable response. Performance: Grrrreat!" From here: http://www.sportcompactcarweb.com/tech/0207scc_boostcontrol/
October 18, 200421 yr So why would one want to change the boost? Will that change HP, or MPG? Sounds like a pricey item. I hope it is a real preformance improvement. -Brett
October 18, 200421 yr More boost= more power... To a point.. at least until you hit the efficiency ceiling on the stock turbo
October 18, 200421 yr So why would one want to change the boost? Will thatchange HP, or MPG? -Brett You'd change your horsepower (gain some) the higher you raise boost (to a certain point due to heat). It's not recommended unless you are familiar with all the pro's and con's of raising boost. I'm being very general with my answers. This may be getting off subject though so I'll stop here.
October 18, 200421 yr Author Looks like Kevin and Calebz has answered Q's....so I have one left. I am stil playing with what is best for high boost. I know it will be between 12 and 17 PSI.
October 18, 200421 yr welcome to the world of electronic boost control! heh i wills tick with my apc box <its cheaper by far> or maybe met my megasquirt run boost duty as well hmm... after all i did have some help in creating the boost controller code should put my apc to shame
October 18, 200421 yr oh and you will notice your turbo spools much faster and reaches max boost quicker at least you should...
October 18, 200421 yr Looks like Kevin and Calebz has answered Q's....so I have one left. I am stil playing with what is best for high boost. I know it will be between 12 and 17 PSI. 17 PSI on a stock turbo is kind of a waste of effort.. well past max efficiency unless theres been some serious rebuilding and polishing.
October 18, 200421 yr 17 PSI on a stock turbo is kind of a waste of effort.. well past max efficiency unless theres been some serious rebuilding and polishing.Aha! So that would be the answer to the detonation and timing being retarded. Too much heat! The efficiency range of the stock turbo is around 13psi right?
October 18, 200421 yr Aha! So that would be the answer to the detonation and timing being retarded. Too much heat! The efficiency range of the stock turbo is around 13psi right? 13.. Maybe 14 if you have a good IC and a really nice low mile turbo or fresh rebuild... Beyond that you're just pushing a lot of hot air
