After writing an article on Megasquirt in Fast Ford I had loads of phone calls asking if i could sell supply people with ready built units. I couldn't do this and i was struggling to recommend someone reliable that could, until now.

Phil Ringwood wrote most of the code for the comonly used extra version of MS so has vast amounts of experience with MS. He has now started up his own ready built MS supply service. His units come with every thing you would need - software, serial lead, map sensor, short loom etc. He is based in Norwich and will post to UK and EU.

I've just just had another V3 ECU of Phil with nitrous control, switchable maps, boost control and a 4 bar map sensor. the quality and service were spot on.

Note: This is not an advert. I have no connection with ExtraEFI. Simply aware that a lot of PFers are trying the MS route but struggling with supply.

Thanks for the tip Doug

260quid? Hmm, maybe EFi V8 Turbo is a good idea after all?

12x12 map? How tiny is that? I dunno. I mean, i still need an ECU for the GTR too...

And the S13 would be nice too...

What gets done with regard to loom etc?

I freely admit electronics and ECUs confuse me, hence my love of blow thru carbs

Tom Baxter

Thanks for that Doug may give him a bell was looking at unichip but this Megasquirt seems interesting.

12*12? :S

Is that all they are still, i thought the more modern version were more resolution than that.

Garage19

144 sites will be adequate as long as you set them up correctly.

As for suitability for V8s, Phil is your man. He runs a 5ltr TVR V8 with 8 x throttle bodies on MS in his cobra.

A short labled loom is supplied with the ECU. Basically just hook it up to your sensors. Very easy.

Rick

12x12 is plenty enough

JohnnyB

I bought one from this man, all I can say

Great service

Garage19

I usually make the best of the 12x12 sites by clever use of closed loop on any idle cruise sites.

I agree that you can probably do "enough" on most basic engines with 12*12, but its not really ideal when you are using MAP vs RPM imho.

Better if you didnt have to make the sacrifice of less resolution in certain parts just so you can have it where you need it most.

for 260 quid though, you really cant complain

Be interesting to hear Stu's view on the old MegaSquirt.

I've got a Megajolt I've been dying to try out as a replacement for my old Lotus Twin Cam Dizzy..... but have been a little nervous as many seem to scoff a the old MegaJolt/Squirt thing as if its some sort of a toy.

Garage19

Like you say, you can just bunch the load/rpm points up where the big VE changes are.

I'm not saying its the best ECU in the world, but it can certainly hold its own i the sub £1000 catagory.

and for £260 there really is no excuse to be running jetronic on a tuned RS Turbo!

Rick

You can move the rpm bins anywhere which is good. The closed loop target map is good with wideband

Stavros

Yeah you can, its called blinkers, or "my tuner said so so i belive him"

Garage19

I have run a megajolt before on a pinto with bike carbs. As long as you mount the timing wheel /sensor well, you will have no problems.

Stu wont touch them to be fair, i cant blame him, he dont know who built up the system or anything, he dont want to be held responsible.


Im going this route for my twinky turbo so i can use 4 injectors and coilpack

I'm pretty sure some of the Cossie ECU's are only 12x12 point maps..

So who WILL map the Megasquirt? Anybody on here cuurently running MS,and at what state of tune?

Rob

Tom Baxter

I would also like to know who can map the Megasquirt fairly close to me in the Lincolnshire or notts area.

EIL132

Love the idea of Megasquirt, chance to have a play around DIY style and learn about mapping. If I still had the RST I'd be buying it

Rick

To be honest, 250 quid or 500quid, doesnt make much differene in cost. You still need somone to map it, and that costs.

richm

£250 towards mapping cost
The attraction of this piece is for those interested in doing their own mapping anyway IMO

OvaBoost

Think my dad helped with this article in fast ford down at mech motorsport

Garage19 will, and from what ive seen/heard about him doing so, he'spretty fucking good at it

Ive not mapped on it yet, but will be doing an N/A car on it in the next few weeks, so will post what i think of it compared to other ECU's ive mapped with.

neilm

I know Stu wont neccessarily map one, but would be interested to hear his view on whether the 12x12 spark, 12x12 fuel is enough and is the sampling rate of the processor enough etc.


I think the boys at Northampton Motorsport will have a crack at one.....

Morning Fellas,
As has been stated, we wont map a megasquirt under normal circumstances, and this is NOT because we think there is anything wrong with it, but rather because we are not happy about the build quality problems we have seen over the years and ultimately decided to no longer support it.

The problem immediately apparent is a LOT of them are assembled, at component level by people who do not know how to solder or understand the basic techniques required to make the components connect reliably.

Can you imagine the result a poor joint would have on the injector driver itself? Low current to one injector, maybe only when teh ecu is hot?

And who would be blamed if one cylinder detted itself to destruction?
Yes, always the mapper.

12x12 has to be considered a bare minimum for good modern mapping without too much compromise, although i would far prefer 16x16.

Here are some basic Marelli maps to give you an idea what you would get from your available size.

I agree, if there are issues with the build quality, fault finding can be a pig and take hours.

All the ECUs Phil builds are tested on his unique test bed, the same one the code was developed on, and then soak tested under load for a minimum of 12Hrs. The PCB is then coated in laquer to protect it.

I will only buy fully built ecus from Phil because of the reliability that he has introduced and quality control he uses.

Now we are talking. That would add a different slant to the discussion then as far as i am concerned.

for 260 quid,,, its a steal,,,

Anonymous

Sadly doug, most people would sooner have a shitty one nailed together for 200 than a decent one for 260.

GARETH T

im not bad on the old soldering iron,, i would i pay the extra to have a fully tested unit

Anonymous

Likewise, madness to DIY it if its for anything other than the fun of doing it, if its an engin you actually want to work reliabley, its money VERY well spent to pay a little extra

JohnnyB

They great from Phil.

He asks what you want it for and then specs the setup to suit you.

The kit comes with a nicly done short loom and all cabling and software

I payed 260 for mine

Garage19

You are right, unfortunatly.

BlueSmoke

Stu, maybe you could map the ones done by this Phil guy if people have a proof of purchase from him?

Would probably need to see some kind of testament to their reliability over time though.

Anonymous

If Stu is ever short of busines im sure he will consider that.

As it is, im sure the last thing he needs to be doing is entering the budget end of the tuning market.

I cant see people wanting a top quality MSD livemap for 600 quid on their 260quid ECU very often.

Would be a better thing for someone else who isnt already one of the countries leading tuners to get invovled in, like Doug

SafeChav

I may have a go with one of these

GARETH T

why you crying for? i think for the money its a cracking piece of kit
