More detail on www.techedge.com.au

Any other guys building, buying or using A/F ratio meteres it would be good to compare our experiences.

SK I've been thinking of making a kit for a while to fine tune the PFC, so good luck and I'm keen to see the results. This one must be alright to interest you so it could be a winner.

Does it specifically need the LSU sensor or can the famed Falcon one from the Silicon chip book be an alternative given JE's findings?

Thanks, for that SK, I was planning on putting one of these together for the PFC. This (and the link) gives me a little more direction. I'll post up my results when I'm done.

Hi guys, I brought the tech edge kit 3 years ago and have brought the later model one 6 months ago. I built both of them and have found them to be excellent in form and function. I output the 0-5v to my FC-Datalogit and datalog AFRS whle I tune on the dyno. Also useful for checking 4WD's on the road as we only have a 2wD Dyno Dynamics dyno at work.

Great product!

H谋 SK

Just read your reply 谋n the other thread AFR'S and good old knock - I purchased the 2e0 k谋t about two months ago (about 350AUD 谋f I remember r谋ghtly) but w谋ll have to wa谋t unt谋l december when I arr谋ve back from overseas to assemble 谋t.

It'll be great to compare - I was look谋ng at the LM1 from Amer谋ca but 谋t was all gett谋ng a b谋t too expens谋ve for what we need 谋t for.

Cheers

ive got the 2a0 in my car right now rigged up thru the greddy e-01's analog input.

so far works a treat and i can use it to limit boost (well boost other than gate) via the e-01's on board limiters.

its a very nice unit indeed but it does take some time to put together and debug properly, but once all is said and done its mint.

as for the o2 sensor i got mine from the local vw DEALER for 65$USD, pretty forking cheap for a wideband.

Well, I gotta say Tech Edge delivery is pretty good, received my order via Express Post this afternoon. They are not shipping the 7057 lambda sensor any more, I received a 7200 instead. Which is not such a bad thing as rumour has it the 7200 is a bit faster in its response.

I won't have time to start on the kit today, maybe tonight I might lay out the parts and check the intructions thoroughly. The kit doesn't ship with the instructions, you have to download/print them from the web site. Luckily I have good quality colour printer. I will start on the display as it is a little smaller and has less components, so I will have a chance to get used to the terminology used.

;) cheers :D

After a couple of hours of soldering and assembly and the LD02 display is finished;

Tech_Edge_LD02_Made.jpg

I was going to make up the cables after I finished the display, but I can't. I ordered and paid for a 4m cable, that connects the lambda sensor to the WB2A1. But when I checked it a 2.6 metre cable was supplied. This is a good chance to check out Tech Edge support and problem recovery. Email sent 3.30 pm Saturday.

;) cheers :)

If you already have a Power FC and FC datalogit you could get the LC-1 which is a plain WB02 which has outputs for standalones. Costs about ~260AUD with sensor.

You really don't need all the extra displays, inputs, etc the expensive WB02's come with. The datalogit or other standalone will already display and and have inputs for whatever you want.

Very impressed with Tech Edge's response to the 2.7 m cable instead of 4.0 m cable error. Sent email advising of problem 3.30 pm Saturday afternoon. Received email response Monday morning at 8.45 am. Promised overnight replacement which arrived today (Tuesday) lunch time via Express Post. A prepaid, addressed, Express Post Envelope was included for me to return the 2.7m cable.

Now that's good recovery from a problem.

:) cheers :)

PS; I have not told Tech Edge that I am writing this review, so this sort of response should be considered what anyone will receive.

nice work Gary. looking good mate. how many WB02 sensors/meters do you need!!!:)

We sold one with a race car recently, so this is a replacement. We only have 2, the other one is a Motec which stays in the dyno room (under pain of death).

Why did you get the 2AO instead of the more compact 2CO controller?

I wanted the 1meg of data logging.

:) cheers :)

is there any difference again in using the 7057 (7200) over the 6066???

also where on the site do you order the DIY kit?

Currently working on a diagnostics unit for facotry ECU's that was in Elector magazine (if anyones interested), once thats done i'll be onto one of these, albeit a 2E0

we have one i a 4agze rally car and as previously mentioned had some response issues with the lambda sensor we were originally running the 6066 and upgraded to the 7057 and there was a markable difference so I would say the 7200 will be better again. Initially had some problems with noise and interference again I think it was contributed to the sensor, also moved the unit to a more secure position. Awesome bit of gear for tuning a rally car which are more tempremental to climates (full rain days to desert racing with 40+), and also mid range power and low down torque are more important as there is so much more on off throttle, and this is where we were able to make gains rather than sit on the dyno for hours trying to simulate real driving or just doing full power runs for tuning!!!

I know I am no wizard at making up cables, so I figured I had better do that early in the assembly process. So last night I made up all of the cables;

Tech_Edge_Cables_Made.jpg

The PC cable was pretty easy, only the 9 pin plug had to be attached. I used a cigarette lighter plug and cable I had lying around for the power cable, just soldered the 2A1 plug on the end of the cable. The cable for the lambda sensor is quite tricky, the instructions are good, but many pages when printed out. I had to refer back to the TE web site a couple of times, as the instructions printing doesn't include the attachments/links. So I had to go back and print each one of those separately, that was time consuming.

I think TE must believe that I would be making up the kits in front of my PC, but that's not the case. I don't fancy soldering and heat shrinking on my desk in the office.

Tonight I will get into making the 2A1 itself.

;) cheers :)

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 馃槀 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
