Looking at buying the ecu for my let very soon,

There are a few to choose from and there are so many extra that will probaly never get used, just wondering on people choise and opinons

no real budget in mind yet, not sure who will be mapping it but it will be going an engine dyno before the engine goes in the car !

also thoughts on running 8 injectors ???

why do you need/want 8 when there are sets of 4 that will cover the fueling?

yes there are but what maybe be ideal for the top of the rpm may not be ideal for lower rpm or idle.

Im not a massive fan of 8 injectors as its something else to go wrong, and you have to be very careful with managing the changeover when mapping it etc.

But that said, done properly, it does give some small gains over 4.

My personal choice for management would be Autronic SM4, but it depends on budget.

As already discussed, Motec

That said choose who's mapping it and go from there.

I agree with the 8 injector setup to a point, I would depending what inlet your using have the revision fitted for another 4 and have a 8 injector loom made. The Jenvey inlet looks the part and can accomodate it.

That said I don't know enough about mapping to give exact reasons why, I have spoken to people before about the setups though and reasons why and I can see the benefit if its done right as Chip said.

Sounds expensive but doing things twice will cost even more !

Link G4. either an Atom or a Storm..

about time someone actually used these excellent pieces of kit.. rather than old outdated (slow processor) gash.

the only two ECU's to offer the high speed and resolution at the minute other than the Link G4(Rick: link and Vipec are the same product) are the very high end Motec and the Syvecs (Solaris)

jonboy.. what is your experience with management? esp the motec..

chip.. autronic not mean pony trigger wheel?

Browney if you want results then i'll personally fit and basemap it for free..

if you use the smaller ECU of the two (Atom) then you'll get 4aux outputs and 2 freq inputs. plus full sequential control.
the larger ecu (Storm) will give you everything plus extra temp logging channels (direct EGT, oil temp, box temp etc safety trims).

the safety parameters that the Link ecus employ absolutely destroy both the other ecus above..

pm if interested..

No personal experience, not have had with any ecu really, I base my judgement on what I have personally known people to get good results using.

It doesn't mean there are no other ecus that would do the job though, either way choose who's going to map it then sort the ecu out.

Martin, what do you mean by "pony trigger wheel"?

Do you mean it requires a better quality one than the standard vauxhall shite?
If so then yes ideally, although its possible to get it to work on the vauxhall one but its really not worth the hassle, anyway I thought browney was going for a decent crank in which case he CANT use the standard vauxhall wheel anyway as it doesnt fit on arrow/dk cranks in the first place.

The Vipec's seem ok, but I much prefer the software on the autronic TBH, would settle for either though quite happily as both are perfectly well up to the job.

how is the standard vauxhall pick up shite? its not..

tbh the vipec/link is much more feature/safety strategy rich.. and cheaper..

to answer a question. Yes Browney is using a arrow crank. also a dry sump so will have yet another pully down there.

SBD do a trigger disk for the dry sump setup that should work on any decent aftermarket ecu anyway, so at least that side of things isnt a problem smile

As fenny says it on a steel crank, The sbd setup only comes in multi-v setup and being in nova it needs to be on single-v but that is the least of my problems PMSL

With regard to the inlet i will be running and sbd throttle bodie manifold or a qed one and some qed spacers so to have 8 injectors is not a problem.

i have no experince with mapping/ecu ect my self, but i will be buying something that is tried and tested not some thing that is new and still in the development stages Thumbs Up

tfs.. which one??

link is not in development.. it works.. its awesome.. end of.
i got it on both my nissans a friends esc cos and europes fastest RX7.. enough said really...

to add to the above comment.. choose a mapper then go with their prefered product... the mapper could be amazing... but if only uses shite ecus then that sucks..

any mapper worth their salt will be able to tune any system.
