Nope. All in the plan

Just to be clear, I meant the bent rod :lol:

Apparently quite normal for SE's, was surprising to me too.

Which rods/pistons did you go with?

Surely these are perfectly ok if that one rod is straightened in a big vice?

Nope! That one was killed in action.

To be honest, I don't remember. I gave Dann a shedload of money and asked him to make it fast :twisted:

Still waiting in Haltech to finish the patch loom for the ECU. But hopefully not much longer.

More power means better traction required

Ready and waiting to go.

Its alive...

Like Ians car this is the most stock build possible that should surpass 300rwhp like its nothing.

Should be off the dyno by the end of the week and the basemap from Emily's Elite1500 ecu is awesome, just perfect starts, idle and response so far.

Can't wait to see the results of this build!

Postby **NitroDann** » Tue Oct 20, 2015 9:40 pm

The last SE with my new manifold/downpipe combo with my tune went 270rwhp with a T25 and a 2.5" exhaust, this has a GT28RS, and one of my 3" exhausts and an Elite, rods etc etc

I am as excited as a fat kid in a candy store.

Was great to hear the engine running yesterday, abs goes to show the advantage of using Dann for the Elite install. Other than issues with Haltech, the experience that he no had with this ECU seems to be paying off. Apparently the car started and ran beautifully.

Here's hoping the rest of the tune goes that easily.

OMG!!

Here come "JUDGEMENT DAY"! :frown:

I wanted to put an update in for this car, and also add some much needed info regarding Haltech Elite ECU for these models.

Juicys car now works just like it should and despite have a 350rwhp capable clutch was dríven by a 22 year old girl flawlessly and she wasnt able to tell that it was modified, clutch, starting, idle, throttle response, air con and fans kicking in, its pretty much flawless and in many ways better than an OEM SE.

Haltech Elite:

After a pretty long day working out some bugs and inconsistencies between this one and the last install I did, and after a long talk with one of the tech guys I've found a few things.

The MX5 is not officially supported by the Elite in any shape.

The only Elites that have ever been installed into SE's are the ones I have done, this shocked me because Ive heard reports of others.

Haltech has no patch harness in their system for any mx5/elite combos. Any and all harness's are currently hand made based on notes and as a result no 2 harnesses are the same.

The Elite ECU has reprogrammable outputs and inputs, which means you can swap many of the wires in the harness and then you can just tell the software that you swapped them and it will work, this means that the process for building a harness for this ecu is vastly different to older generation ecus...

Example:

In an older ecu it might have 20 pins on the ecu to connect to the cars loom.

Pin1: Crank trigger input
Pin2: Coolant temp input
Pin3: Thermofan output etc etc

In the above example when you make a harness for an MX5 you MUST connect the fan wire to pin3, because its predesignated. With an elite you connect the fan wire anywhere and let the ecu know.

IE: Pin1: generic output
**Solder thermofan output wire to pin1**
"Haltech software, pin1 is for turning the fan on!"

So you can make a patch harness for an Elite a million different ways and as long as the software matches it will work.

The implication is that you have to have the right tune to go with the right harness, which means that the harness guy has to create the right tune for you and you start from that point.

I didnt know MOST of this previously, and I assume nor did anyone here. What it means is that the next Elite I do I will actually make the patch harness myself from my own patch diagram, to suit my own base map, and the cars will work perfectly first go.

Whats nice to know is that I actually was given a generic harness and tune twice, and both times I was able to create a correct harness and tune and get the cars to run excellently.

I guess the next step is working out if people are interested in Elite plug and play setups which include a PnP harness with PnP boost control and the injectors/map to go with it and run your car like stock but with tonnes more power and drveability with almost no tuning. I have the harness info, the ECU side of the harness info, pinout combination that works with that harness, and a base map that works flawlessly like stock with a specific set of off the shelf large injectors.

In the end the Elite is an amazing product that can run so many stock and better than stock functions in such an amazingly smooth and precise way, and the frustration has come from misinformation both propagated through the community, and between myself and the exceptionally busy guys at haltech.
Again Ill remind people that Haltech is a really small company who has only 6 technical guys in the whole business, so to be able to get one on the phone for an hour this afternoon is great and I really appreciate it. However this had led to some frustrations, and misdirection. There is no plug and play elite, and so far Im the only guy who has managed to get these into SE's. But there could be others who can get these fantastic results, I have all of the notes and info required to build plug and play kits.

Thanks for posting that explanation Dann, please post it in a separate thread too (with an easy-to-search-for title) to make the information easier to find and post it in MT.net too.

It REALLY annoys me when ECUs are advertised as "Plug and Play" when clearly this is NOT the case, there are "gotchas" that MUST be addressed before any tuning is commenced. I assume manufacturers do this to get more sales but surely it just generates negative feedback when there are issues which is a much bigger issue these days given the impact of social media.

I've been meaning to ask you too to post your opinions on ECUs since you've seen a few now (MegaSquirt, Haltech, Adaptronic).
