Standalone ecu

michaelb · July 31, 2018, 08:04

Has anyone had any issues with other car functions after installing a standalone ecu? E.g. any warning lights on etc?

Nope

Ok, good stuff! The guy about to do my work said that it's not uncommon on some cars

Depends how clever he is with using the stock ECU.
If he can run the stock dash with an aftermarket ecu, he's the first one to do so

michaelb · July 31, 2018, 12:59

What do you mean mate? The dash? All the gauges etc?

Yup.
A lot of the communication in the car is over a Toyota proprietary protocol (BEAN). Nobody has cracked it.
Particularly the water temp and rpm gauges don't work without the stock ECU.

Also the immobiliser requires the stock ECU to be used in parallel if you want to keep it.

So as long as your guy uses the stock ECU correctly in parallel, all will be well

I'll need to let him know then! Or would everything work if I went for a piggyback?

If the gauges don't work, surely that's an MOT fail?

Depends what you're trying to achieve. A piggyback is an option. If you live near Essex I have a lovely Unichip Q+ for sale

I'm not sure actually. I guess so.

michaelb · July 31, 2018, 13:26

So what do people do if they've installed a standalone? Swap it out for the MOT? A piggy back I assume could just be unplugged?

I saw yours for sale mate! I'm going to get whatever I need off the guy doing my engine conversion as he'll give me good discount since he's doing the work

If your guy knows what he is doing you will be fine.
Any 1zz or 2zz that is running standalone uses the stock ECU for dash.

If this something he hasn't done before then some research may be required.

If you go for a piggyback everything still works but you won't gain as much.
I've gone right off piggybacks. Hard to make good power with them on Toyota ECU.

michaelb · July 31, 2018, 13:28

I don't think he's done an mr2 before, he's used to tuning race and rally cars

The Power FC is a standalone for our cars (will be selling mine soon) as I now have a Link Xtreme plugged in - its actually running as a piggyback but the stock ECU just looks after the body controls, all the fueling, timing etc is run via the Link.

michaelb · July 31, 2018, 13:35

I'm looking at a link one already mate or another one that my guy suggested -

"Motorsport Electronics...

ME221... £695 with loom

This is a great budget ECU. I have used these a lot with MX5's and I am currently fitting one to a supercharged Honda S2000. This will run the engine and control VVT etc also. Certainly one to consider.

ME442... £1095 (special introductory offer). I haven't added this to my own website yet as it has only been released, see details here. This is the new big brother to the ME221. This will do everything you need and more. The normal retail price is £1554 so this is a superb deal."

Ecumaster EMUBLACK is the way forward. Especially as we have a group buy going with Greg from RRR near Cambridge.

He's now done 4 MR2s of different kinds so he knows what he's doing.
And 1200 all in for ecu, fitting, mapping and a data logger

michaelb · July 31, 2018, 13:42

I know all about the group buy mate, but I'd rather go for one my guy already knows and uses.

Apexi Power FC runs em all standalone

Pfc is indeed the only one I know of that can run fully standalone.
But it's flippin ancient.
It "gets the job done" but that's about it.

Hell, it's almost better for N/A than it is for turbo

michaelb · July 31, 2018, 17:03

I've decided to just to do the 2zz swap with se7en cams, do I even need a standalone ecu at this stage? The swap comes with the corolla ecu.

Get your mate to do the swap then drive to RRR to fit the EMU Black.
For 1k it can't be beaten.
Without a new ECU you won't get the full benefit of the cams.

michaelb · July 31, 2018, 17:08

My drive to RRR will cost me about £400 mate! Lol I have to get the ferry across the Irish Sea! I want to put a wide body bodykit on the car too which is going to cost a fair amount after fitting and painting so I'm look to save where I can

I may need a new exhaust as part of the swap too which will add another 600-700
