aftermarket ECUs

and the vw stuff is pretty fast, and free.

However without serous mods, there is no point in remapping it

for small capacity a turbo will give the most bhp/

 

Chipwizards - 250 for a remap.

 

Right, it really does depends if you're going to run it naturally aspirated, or forced induction to what ECU you choose.

As for having a base map on emerald as benificial, not a hope in hell im afraid, you'll be able to start the car and thats pretty much it, it won't idle, rev freely or anything.

Emerald is an perfectly acceptable choice IF you're going naturally aspirated, and dave walker will map the whole car for 240. I garentee his rollers are miles better than jabbasports, TSR's, stealths etc etc.


They 1600's have the potential to be a cracking revvy monster of and engine due to the short stroke of em.

 

ive seen his car, totally stripped the roof lining and carpet, all out just a cage and buckets and the dash (airbags also out) i know he will have money to do what he wants just not what other people want

 

bodge a ko3 on it and run it on a g60 ecu, best bang for bucks

 

What I don't understand is what benefit you are looking to get from running a programmable ECU when no work has been done on the engine. Surely it makes more sense to do whatever work you want to do on the engine first then get the ECU mapped afterwards, or have I just completely mis-understood?

 

You're half right edc, electronic mappable ignition on a car that uses bob weights to advance the ignition will always give better power in general. for modern ignition/forul systems, you're right.

 

witie, get some bike throttle bodies then get designa dubs to sort the ecu

 

correct TT, P.S. hows your project getting on?

ok, i wasnt going to go into this, but it seems i need to
the spec i was going for was:

AFH 16v head,worked on

256 or higher cams

45mm TBs , 120mm trumpets

rebore/restroke to 1800cc

lightend balenced bottom end

6spd lupo box with different final drive


now as i said, this was just to put me on for a while
as i also said, 75bhp from a 1.6 8v is a bit down

so is the general idea that i wont gain much....?


idea has now changed for the head, but im keeping that under wraps.....as my mind is always changing
and im not sure if it will work...

comments are helpfull, cheers

 

i looked into doing a 1.4 16v turbo for a laugh, but really should do
my big capacity 20v first

 

this was just a question as to whether i should go on a base map
for a while untill i build my small block,
i have my plans and im sticking to them

 

should run on a generic map if all the sensors types are
configured properly

well enough to limp it to a RR

 

so thats a resounding no to gaining owt on a base map
over my OE ECU and its map,

ok, thanks to everyone that replied.

 

... well I would say 100bhp from a VW 1.6 8v engine ain't bad considering the 1.8 gives 90bhp and the 2.0GTI gives 115bhp

 

Have any of you tried building the megasquirt ECU?

 

Sorgs 1,6L 8v with ported head, throttle bodies, Weber throttle bodies and Weber Alpha ECU puts out 136 bhp

 

45s are too big, mate lose the low end a bit on a 1.8 40s will be ample

 

thats my point polo classic you have to spend out serious to get 136bhp from a 1.6

when you could use a 1.8 16v costing 200

or a 2L 8v with a flowed head and cam for under a grand.

I didnt do A level economics for nuttin lol

 

That's all well and good but some ppl just want something a bit different.

 

thats what i thought, but my friends in the 20XE world assured me
45s would be better then 40s on a 1.8 16v..... confusion

is there no maths for what dia. for what cc, etc?
