Stand Alone Management

[tom_beverley]

I've searched the forums to get a little knowledge as I've never looked into this before as I was planning to run a 1.4SR dizzy and assumed that would be ample.

To get the most out of my engine would it be benefitial to have stand alone?

With stand alone is it possible to not have a distributor at all?

[Stuart]

which engine?

stanalone means you can run wasted spark using a dispack (or even coil on plug)... so no more dizzy, OR you can use a GTE/GSI "dizzy" (its a fake one) if you can get a single coil driver ecu cheap.. (but thats a poor way to go imho)

Sorry forgot to put that in :wall:

Its a E16SE on T40's so what would I have to acquire to run it distributorless and would it have its advantages?

[Welsh Dan]

The advantages would be that you can map the ignition timing curve so that in theory you could get more power, because the mechanical distributers are a fixed curve that has been set up for the 1.2/1.3/1.4 engines in standard form.

I've not read into this stuff too much, but I expect you'll need the dispack setup from a C16SE, the standalone ECU and the loom to connect the ECU to the engine.

[Stuart]

tbh the cost involved would kinda outweigh the gains over the 1.4 dizzy setup... granted you can transfer the ecu to almost any vehicle and in the long term they dont lose much money but still the mapping cost cant really be recouped.

Thanks for the info,

But, having just built the engine up I'm going to have it RR setup. My dad can get the carbs well setup but I really want/need them spot on so at the same time they could do the mapping? As I've read in other threads its best to ask the RR which setup they prefer. Yeah, I thought about the ability to transfer to any future engines so it appears a bit more appealing.

Make sense?

Could anyone elaborate a little more about the parts required?

What gains could I see roughly, about 10-20bhp?

[Stuart]

hmmm dont think you will get 10bhp to be honest., add a lairy cam and you might.

ECU's... an EXP (or EP cant ever remember) 48 DTA now its an "old model" should be ohh ?450 ish, a loom DIY is about ?50-80 or purchased ?300.
mapping is approx 50-100 per hour... look at about 5 hours worst case

You can have the 1.4 dizzy re-weighted to give a different advance curve.

To switch to wasted spark youd need quite a few things, crank sensor wheel on bottom pully, crank sensor and bracket(also may need an oil pump change if yours doesn't have the crank sensor bracket bolt hole), tps fitted to the carb spindle, and probably air intake temp sensor/coolant temp sensor.

The effort/cost is not worth the gain imo.

If its an ignition only ecu it'll also mean you cant fit tb's or something and use it to run them as it wont control fuel.

[tom_beverley]

Thanks for your help Stu, I will get there eventually....

I'd have a crack at the loom myself, shouldn't be too difficult, but tbh I'm not very genned up having only had dizzy run Nova's.

Really fancy doing this (with whichever setup is most economic but with good features) but obviously need to gather as much info as possible as at the moment this is all new to me.

I was looking at the MBE 967i kits, are they the same thing? At worst I'd look into a mappable ignition but I'm assuming the same amount of work will be required.



The effort/cost is not worth the gain imo.


Agreed there if you tally it up to circa ?1,000. Oh the quest to get something a little different. The effort isn't a problem I'd be willing to have a good go at this but only want to do it once.

Never heard of this, any more info?

[Adam]

Theres a company that can change them, but i cant remember what they are called. HTH ignition systems or something like that iirc.
I think Jim had his re-done on his 1650 T40d 8v.
