3k Diy Stealth Efi Setup

[Taz_Rx]

Good work mate. :P

 

I've just also installed EFI to a K myself. Much more fulfilling when you know how everything works and you did it yourself hey!?

 

Also like the fact you've put that stock air filter back on to hide the EFI and keep it looking all stocko, same with what you've done with the coil packs. <are those a waste spark dual coil, or 4x individuals?

[brodie]

Yes it is a wasted spark, dual coil.

NICE. love the fact from the outside it looks bod stock. any idea how much it all cost??

 

CHEERS

Very well done :D

Would be interested to see some power figures when

you get them.

My uncle has been trying to convince me that this would be a good

idea for a while now, interested to hear more about the process.

" any idea how much it all cost??"

 

Hey. Mmm, maybe best for me not to think about the answer to that question :lolcry:

 

To be honest I spent WAY more on this than I had originally intended. I'm probably about $1600 or so out of pocket for the whole conversion. However I could have done it quite a bit cheaper if I tried by using used parts etc... I have bought most parts new where possible or totally rebuilt what I couldn't get new. I've had to buy 2 wideband oxygen controllers because one unnamed brand continually failed for no apparent reason, and I needed something consistant. USB to serial converters can be problematic too as I am discovering (and expensive buying several until one works). I spent too much on the fuel pump too :)

 

But at the end of the day was it worth it? Totally. It's starting to get into colder weather down here lately, mornings are about 10 degrees C. It starts first turn of the key with no pedal and idles perfectly. It drives great when cold. Fuel economy seems good, low down torque is markedly better, and overall the engine is much smoother. AND I've just added one-touch start to the ECU, so one quick flick of the key to "start" and it cranks until it fires, all by itself. It's certainly brought this tired pushrod engine into tis century...

Brodie, top work mate.

 

2 questions: are those HM/Perry headers?

 

Did you use the Innovate LC1 wideband o2 sensor?

Thanks very much. :o

 

As for the headers, sorry I don't remember for sure which brand they were and couldn't find the invoice for them, but I'm pretty sure they were a pacemaker or similar, they're 4-1 and to be honest I would have preferred 4-2-1 - but they were really cheap @ trade price at the time so I couldn't resist. They fit and work well anyway and were only about $150, was very loud with them ending under the firewall while i drove it to the exhaust fitter to have the flange welded to the rest of the system. :(

 

The wideband is a whole other saga. I did buy an innovate lc-1, it failed in the first 24 hours, dead. This was very frustrating as now i could only attempt to dial in my freshly-injected engine by ear. Having posted it back to the usa at my expense I received a new replacement within about a month or so, but without any explanation. The replacement unit worked great for about 3 months , then it started behaving oddly one day and within a day of the symptoms appearing it too had died totally. I sent it back to the usa again - at my expense and am currently waiting for its return. Unable to accept the unreliability of this i bought the cheapest techedge product I could find, a 2j1.

 

Let me add that the innovate product was functionally a very nice piece of equipment, just electrically fragile. The techedge product so far seems a little more robust and accepting of voltage fluctuations, and unlike the innovate is much easier to mount the controller in the cabin instead of the engine bay which pleases me. IF you are looking to buy a wideband take a look at the techedge gear, its made in australia and although some of the products may not be as cosmetically pleasing as their competitors they seem to work well.

 

Hope to go for a long drive tomorrow to let the car tune itself!

 

Cheers, Brodie.

Mate, I'm glad I asked the question before I forked out! I'm familiar with both the setups, but looking at the techedge site, I wasn't sure if they are still making them (the site is about 15 years old as far as looks go!)

 

I was erring towards the LC1, but now I'm not sure. So it was the wideband controller that packed up, not the actual O2 sensor (which are bosch items?!?)

[brodie]

Yeah, techedge is still there and in production, the 2j1 is a newer product at the low end of the spectrum but still nas 2 independant, programmable outputs, same as the LC-1. I use the 2nd one to drive an LED panel voltmeter, with 9:1 set as 0.9v output, and 22:1 set as 2.2v output, so when you move the decimal point of the meter across you have a very cheap AFR display. If you are tossing up between the two, I say buy the Techedge, every time.

 

Yep, they both use the bosch sensor, I'm using the one that came with the LC-1, apparently now there's a newer replacement for it that has faster response times which will plug-in to the 2j1 when my current one dies, no need to replace yet though.

 

Went for a drive last weekend, pretty much finished dialing in my VE table, quite pleased with the overall drivability now.

 

 

My latast project involves having the laptop display on my in-dash tv, this gives me 8 more gauges, in real-time, on the screen, just leave the laptop on the back seat as a processor (no one ever sits in the back anyway). I have it working. Will get some pics up soon.

 

Cheers, Brodie

[brodie]

PS if you really do want an LC-1 i'll do you a good deal on the brand new replacement I have just received, its in the box, haven't even stripped the wires or powered it up, you'll need a sensor. PM me if you're interested.

[wde_bdy]

I realise this is a rather old thread, but any more detailed pics of how you modded the dizzy? Just doing a similar wasted spark conversion with an MS-II V3.57 ECU on a 4K-E. Also, got any dimensions on the trigger wheel and better photos of the sensor mount?

 

Thanks
