x16xe on carbs info needed

[alan b]

hey guys stripped the corsa today and decided im gona go for carbs twins 40's? anway how will i manage the spark? no managment as on a tight busget! cheers lads

[Stuart]

you cant if youve not got the budget to get even a megasquirt for ?200...

[Adam]

Theres no way you can do it on a budget tbh. A twin carb inlet alone is about ?150.
Then the carbs ?200, rr setup ?300, management ?200 minimum etc.

Tbh id put the money towards a mantzel copy inlet (?200)

[alan b]

half my loom is cut and another bit is fried, it was in a crash, didnt no megasquirt was that cheap, anyone ever use a manta distributer ohc distributer and the little belt jobie

[Adam]

You'd somehow need to bodge on the dizzy, and run it off the alternator belt or something, not impossible, but v.hard to do.
A proper ecu would be much better and actually have a suitable ignition curve.

If your buying ms tho, you could go the whole way and fit bike tb's(same cost as carbs) but more power and better driveability etc.....

[alan b]

just did a little experiment on my sri, if i disconnect the injectors it still sparks, so could i some how fool the x16xe ecu into still sending out a spark with no injectors?

[Adam]

It may run, probably crap tho.
Ignition curve will be a "limp" home mode one as it will know the injectors are unplugged, so naff all ign advance.
The curve will be wrong anyway as it was mapped for the engine with a 5ft inlet tract etc.
You will still need to keep the TPS,Map sensor, Crank sensor for the ecu to fire a spark. Map and Tps you wont have with carbs... Unless you fit them.


Just buy a megasquirt for ?250.
Or Megajolt(spark only) for about ?100.
But then you'll need a map.
It will be a hell of a lot better than imo bodging it trying to get the std ecu to run it.

[alan b]

looked into mega jolt there think il go for that but how will i run a map sensor on carbs? will i have to make up a little chamber? or could i use a tps sensor on one of the carbs?

[maccas]

use a tps, you can get special tps's for webers, have a look on the sbd website, you will see all the components you need for a conversion to carbs and management etc. www.sbdev.co.uk (http://www.sbdev.co.uk) hope that helps

[Adam]

Megajolt uses TPS and MAP sensor to make a 3d map.
A TPS comes on bike carbs, you will have to make a bracket to fit one to the spindle of weber carbs.

For a map sensor you will have to drill and tap a union into each runner, then join them with vacuum hose(with t-pieces) then run a main hose from the end of the join to the megajolt ecu. If its like MS it has the map sensor built onto the board.

[Ash]

just use bike carbs if you haven't bought anything yet. They would work a lot better on a 16v engine than webers. And if you get the right set, should be easier to make work with MS.

[Adam]

Get TB's!
If your buying MS anyway(which will run tb's) i see no reason to stay with older technology, giving less driveability and gains.

You'd still need an inlet etc for bike carbs, so may aswell get bodies on there.

[alan b]

no mega jolt uses a crank shaft sensor and either a tps or map you dont need both!, if i were to go for bike carbs which ones? and also how easy are they to set up, no one over here in ireland wants to set them up!

[paddy138]

were abouts in ireland are ya

[burgo]

ive got an x16xe and bike tb's and ive just received my megasquirt aswell. in total the tb's and megasquirt has cost me ?400 so hardly a bank breaker. ill let you know how i get on in a couple of weeks but let me know if you want contact details of who i got my megasquirt from

[alan b]

im in galway! ya mite go for that then didnt no it was so cheap!

[paddy138]

do you know any rally prep companys up there or near it

[burgo]

the megasquirt i bought comes ready built and the bloke puts a base map on it and sets it up as much as he can, plus i went for the launch control and tacho output option. all together it was ?305 to my door

You cant use the Std GM ignition DISpak/crank sensor to run megajolt.

Need EDIS system off a ford.


I'd still go for MS and tb's. Can be done cheaply if you can knock yourself up a "ok" map, as a base map is just that, to get the engine barely running.

[Adam]

Megajolt and Megasquirt are two different systems.

Your megasquirt will be running version 1 with the Extra code which alloys it to directly fire coils, megajolt cannot do this.
