What ECU for my SE

Postby **NitroDann** » Tue Apr 23, 2013 10:22 pm

Absolutely.

It wasnt the hp i was wowing I knew that would happen I was surprised the whole tune came together so easily and quickly and how well tha car ran on teh ecu/firmware.

Thanks for the info re: wideband O2 sensor.
Sadly no updates from me any time soon but I'm more certain about what I'll be doing.

Look at davekmoores SE that just blew up, it got hot (air and water temp), the ecu didnt pull any timing and the engine mangled itself all over the engine bay, and he spun the car at very very high speed due to the loss of oil.

A safe tune is very important.

Had dave had a MS2/3 the base map he got with it would have had the idle and air con tuning perfected already, the air intake curves and coolant temp curves perfected. The air temp and coolant curves are responsible for pulling timing when its hot and saving things like what happened to dave.

Thanks, Dann, for suggesting I was going at very very high speed!

Hopefully BARMY is getting rebuilt very soon now, with stronger bottom end etc. Plus I guess you're going to tell me it needs MS, not the Haltech?

Anyone out there want a Haltech Interceptor ECU at half new price? I'll only sell it to you though if you are not going to make your car run lots of boost for 60% of a lap - in other words it's right for a road car, not for a track car.

Has anyone here installed and tuned an MS3 into an SE yet?
I'm looking into ECU's at the moment for my SE and I'm still can't choose between the MS3, Adaptronic and Haltech PS1000

Message gslender about the MS3, he's pretty full bottle on who's doing what.

I have a PS1000 on my SP and I'm really happy with it but it will cost you more than 3K to get it installed and dyno tuned. Unless you DIY. Pretty scary though for the novice.
Then there is the new fuel pump and bigger injectors if you want anymore than 160rwkw and you know you will. So your around 4K to do it safely.
If I had the choice to do it again I would be getting in touch with gslander and driving up to see him.

Interested to hear why? I thought you were happy with the way yours has turned out - Assuming it's the percieved significant price difference?

Sean,
I have a slight issue with Idle dip when the lights are on the air con at the same time. Not all the time but I can stop at the lights and push the clutch in and the car nearly stalls. Granted that doesn't happen that often but the revs will fluctuate between 500 and 1300rpm for about 10 seconds and it is one of those things that is annoying me.
All the rest of the time the car runs faultlessly and I should probably not worry about it, but I do.
There is no easy way to change the idle settings for when extra electrical load is applied. No alternator control that you can just set.
We are working on wiring an input to the ECU for when the electrical load comes on where you can increase your Idle target RPM / Duty as suggested to me on the Haltech forum. This is way beyond my technical knowledge and the one person that I know that could do this. I won't give my car to, as he was the guy that put nearly 17psi into my beautiful 20,000km old stock standard motor and bent 3 of the 4 con rods, then said "Sorry man" I only asked him to set to 12psi. So were not talking.

So there is still a little problem that is not perfect and I know running a stand alone ECU will never be as perfect as the factory tune, but this is a common problem with mx5's and I feel it should be sorted by now.

I will contact Haltech next week directly and see if they have anything new for this or a upgrade or something.

Richard.

Not true, and i hope you find out soon

Perceived difference? A $700 DIYPNP MS2 installed in my NA6 idles better than stock. I know this as a fact as I have another NA6 that hunts and dips worse than the standalone ecu I installed.

If you want something that isn't DIY, then buy a MS3 Pro and they're $1200 and offer way more features than the MS2.

Its a common problem with mx5's running Haltech's I should have said.
I actually feel the car is 100 times better to drive now with the Haltech than with the chip torque tune. Its smoother, no hesitation at all and certainly no jerkiness when backing off in boost. If I can just get the idle dip fixed it will be perfection.

Sounds like the first thing to get with an SP is an aftermarket ECU. Factor some time getting it sorted.

Yes perceived. It's not a dig at either product - I suggested earlier in the thread that I like the MS...

Anyhow, I mentioned perceived as it's what $1200 base price for an MS3, vs a shade under $1900 for a plug in platinum 1000 Haltech.

The level of factory and tuner support for a Haltech is higher than that for an MS here in Aus, in terms of it's easy to send the unit for bench testing and reconfiguration, and there are lots of well known tuners who use and like the platform.

I know you will suggest it's all just settings and an MS is easy to use, but the fact remains a tuner not used to it wont want to learn it for free, they'll likely want to charge you for their time in one way or another, and if you have a finiky problem they'll likely drop you pretty quick and blame the MS - even if it's not the problem.

I'm sure the MS3 is a great ECU but I just don't think it is the right one for me. I'm not a DIY tuner and don't plan on being one so therefore I need an ECU that has local tuner support (I just want to drive on the weekend and not finger around on a laptop getting my car to run right). From what I've gathered no one in Australia has installed and tuned an MS3 into an SE yet and I don't want my car to be the test mule.

Looks like I'll be going the Haltech PS1000

That's awesome! :roll:
