Rod's build thread - new title - TSCi
Turbo Mini Forums

Well this MegaTunix is seriously cool.

It has a lot more feautures than TunerStudio and uses tabs for accessing all the menus so is much easier to use.



It's got the realtime display backsame as Megatune used to have but better,


The only downside is having to create your own gauge display as there is no default one suitable for the siamese code but once I got the hang of it, it didn't take too long


Look closely and you'll see I can even have the injection advance gauges the logical way around with advance on the left :)

There are a couple of bugs in it - as you can see a couple of the gauges aren't working - either a bug or I've done something stupid but the author is looking into it already.

(I can break anything.....).

Whilst I was on the Extra forum posting the problem I did spot another familiar name as browsing the MegaTunix section........

Inteesting!

I didnt know there was a windows version of megatunix, I shall have to take a look too.

Not much to show, but just to show I am actually moving forwards...

Wiring for the ECU






With hindsight, the internal connectors in the engine bay are OTT..... the cable runs are so short they could have all been in one piece.


But it will making experimenting with multiple injectors a lot easier.

Just need to put the cables in for the widebands and a mounting plate for the contollers, then it can all go in the car... :)

Finally finished on the inside...



Well, the ECU finished,

Just now have to add the three wideband controllers (one small, two medium size), one of Jean's IO-x boards (which I have yet to order), the traction control module (which I have yet to build) and the Thatcham Cat 1 alarm/imobiliser wiring......

I've ordered one of these,

Yes, I know it's eBay crap, but it will hide all of the electronics and wiring and may even allow me to fit a decent CD player (or ICE according to the Chavs...).

rod see my build thread about my dash (from pg 4), same guy
its well made but just doesnt quite fit right

your doing a cracking job keep it up not far now

You cant sleep either then Rod ?.

well done rod !

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Well the dash won't be arriving today as the tosser hasn't actually sent it.

He states on the listing "more than 10 available". I ordered on Monday.

He updates the Order Panel on Wednesday as "dispatched, 48hr courier"

This morning I get an email "Hi, am very sorry about the wait but i sold 4 dashes in one day including yours and i can only make 1 a day but your is all ready and booked out now with city link for pick up friday."

Why do people feel the need to lie on eBay ???

Most of the wiring now in



The coil of wire at the top and the knotted red tube are for the boost control PWM valve, not sure where to mount it yet...

Inside,


Because the tosser who didn't actually have the dashboard he said he had 10 of, hasn't actually sent it, I can't work out where to mount the wideband controllers and displays plus all the other gauges yet.

Heater is going to be a problem too.....

Also, need some thoughts on the fuel pump inertia switch (currently lying on top of the MS2, see other post).

Schrödinger's cat - so which one am I ???

Rod the build is looking good. I know the feeling of trying to get everything behind the dash so that it servicable.

Did the displays for the techedge take much building? I have a old techedge that i want to use and would like the display. But there is a massive price difference in ready built and kits!

Ron

I built the LD02s, now called DIYLD2_R (or _G)

They were quite tricky compared to say a Megasquirt or even compared to the DIY 2Y* controllers but that was mainly because the PCB is really small and components have to be soldered both sides and some are SMD.

But I would do it again - they use real serial data from the controllers so no voltage offsets from crap 0-5V outputs and are very fast to respond.

The only issue I has was the initial firmware on the CPU (yes, the display actually uses a CPU as it reads serial data) needed its firmware updating and the supplied RS232 serial chips were eratic so I changed them for better ones.

Schrödinger's cat - so which one am I ???

I was going to buy a aux box too use with my lm1 but realised that my Tech edge will do the job. It has a memory so will be able to log runs with it without the laptop in the car.

It sounds a bit to advanced for my soldering skills I reckon. Will have to start saving!

Yes, my 2Y* controllers have the built in memory - I haven't actually tried it yet but the specification is good.

As for the soldering on the displays, I've just been as honest as I can .....

It's perfectly do-able but, in Haynes language, it's a 4 spanner job, not a 1 spanner job.


EDIT......

I've just read the specification of the new version of the DIY display,

"Because LD2B uses some surface mount components, it comes as a partially built kit and requires minimal soldering. Parts that are soldered include the LEDs and photo-transistor, buttons and some sockets, etc. "

In other words, unlike the earlier version (LD02) that I built, on the "B" version they have now done all the tricky bits for you.......

49 Aus$ for the kit or 140 Aus$ assembled..... (£30 vs £85)

Schrödinger's cat - so which one am I ???

Mmmmm - yes, I think I understand,but then again maybe not.

4 spanner jobs I can do, but 4 diodes or whatever you use these days is WAAAY beyond me.

Cant wait to see/hear this running.

First, just for david, I thought I had posted this the other day but obviously something went wrong....



And as for the dashboard....

thinking about it, the initial fit was good, but as i trimmed it about to get a perfect fit it just showed up all its imperfections more

Schrödinger's cat - so which one am I ???

It's a shame it's so badly built, if only it fitted right it would be ideal


But one end is OK


And the other end crap

Schrödinger's cat - so which one am I ???

ouch, i dont understand how it can be made so wrong?
i absolutely love the one i built but i am going to make my next one from scratch it would have been easier i think

Yes i moved to the darkside

Sorry Rod, cant seem to open the file and see the picture of a diode ?.

Build looks good Rod!

Ive got the same dash and it seemed to fit ok. Is the main problem the the gap or the shape?
