The center housing rotating assembly is fairly sensitive to oil restrictions, which include ANGLES. Side to side (along the shaft) you can usually get away with 15-25 degrees. Up and down (through oil inlet/outlet holes) you should really have very little, if any. It looks to me like you have close ...

You have to understand that with a motor, sometimes fuel can get 'stuck' around the rings, some will still be in the intake port, and some will be sprayed 1 rpm before burned. When you cut fuel, that residual gets burned in the following revolutions since you have spark. When you cut ignition, that ...

A real simple way to do this would be to use a 4PDT (4-pole relay, 2 position each). You can get mechanical units for $5-10 from digikey.com; I have a bunch, they are very nice. Mine in particular have a spec of 13 milliseconds to activate, 5A per contact. Deluded's boards no doubt work very fast, b...

Sometimes people accidentally swap the IACV plug with the IAT plug. That will cause a crazy idle, and IIRC it can ruin some circuits. You may also have the purge solenoid plug (if you have one) swapped with something, that may cause issues. Another thing that happens is people swap the outer pins on...

I was just curious about diode usage. If I have a relay that is activated seperately by a switch AND the GPO, would I need a diode between the relay/GPO wire? Or does the ecu already have them in place? I don't want to activate the relay via switch and blow up the GPO circuit. :oops: If I need one, ...

Doesn't ectune have some adjustment for TPS enrichment? Maybe you just have to set it lean, then figure out the lowest TPS you need to cruise, then set enrichment to that TPS range.

If you set a GPO input and a condition like TPS=100%, does it activate when both the input is switched on AND tps=100%, or if either happens, like tps=100% and input=on? edit: I have another question now. I think I can do what I want using both GPO 1 & 2, except both using the same output (IAB in th...

By \"tonight\", did you possibly mean \"two days from now\"? Bad translation maybe??? Kinda unfair to those who don't have interweb access for a short time & follow the rules to the letter. They technically can't roll back their clocks w/o breaking a law or two. :? BTW at the time of this writing, r...

I got some freescale accelerometer chips (the older high sensitivity/5vdc kind) that I've been wanting to use with my SSI-4. Basicly it only needs a 5vdc input, ground, and output signal. A few caps/resistors help it read better, otherwise they're 1/3 the size of a eeprom chip. With no pull on the a...

Thats why you sell the information only. (or post it plainly if you're not greedy like us ) The key is to cover all your bases, make it a DIY deal, and tell them how it is - no support. THe ones who get it will make units for those who don't. Thats how the world usually works.

Just wanted to mention, you can find a chart on the intraweb about how fuel mixture affects emissions. If HC skyrocket, you'd probably want a little more timing (longer burn time). It increases drasticly below ~12:1, and above 18:1 (for whatever reason). CO is supposed to skyrocket <14.5:1. Less tim...

SC's always get me mixed up, plus that was a lot of typing & rearanging thoughts. It would actually force the turbo to overboost to create the same manifold pressure, and it would also be moving through the SC. In most cases, worst of both worlds in terms of efficiency. Using an EBC to control the b...

Since the RMC setup was made for power>smog, he didn't care about how it looked, just how it worked. He has a double-port WG actuator on it so it will open during vacuum (bottom port to manifold/post-SC), and open during turbo-created boost (top port pre-throttle body). He used AEM and a boost solen...

P05/P06 maps that I've seen (pulled directly from respective ECU's) are sometimes odd numbers like 18*. But generally sohc vtec and b-series motors set it at 16*. The reason for this is to, via the EMS, 'lock' the idle ignition value to synch it almost perfectly. It should disable any ignition modif...

I think the largish retangular item right behind the external 28-pin EEPROM socket was the baro. The only use I can see for this is people that travel between high and low altatudes - and even at that, mainly those with turbos. With NA cars, the changes between intake/exhaust are nearly directly pro...
