Early stage of modification, adaptor plate & new spindle

TPS is from VW

Inside are ball bearings from RC cars to keep spindle free from play

If wanting to keep a fiarly standard engine look,

then ye can put the injectors into yer own carb manis.

 

use some bungs welded on, then tek the innards oot the carbs, so all ye got left is the throttles.

this will save alott on manis, an adaptors.

 

TP can be fitted on an extension like Adreas did, but onto a carb end.

or ye can use manifold pressure, to activate ECU, so nee need fora TPS

 

my self, I like the TPS set up.

 

Butt, try and get the Emerald type that can bunch the lower RPM sites together,

then the idle stages are better.

No ECU ive seen has got whats really needed though, and thats to be able to ev a idle line, then a upto seting on TPS say idle 1, then TPS 3 then TPS 6 then the OE setting of 10 TPS, Adreas will concurr,here, as at 60+, ye can be running at TPS 2-3

 

AND there is a Biggg step in fueling from the idle sites 1 TPS, to 10 TPS, say at 1200

its 45 and at 10 its 150, but frae 10 to 20 TPS, there only 20 odd points up.

 

butt, look into using yer own manis, air boxes first, as it,ll save ye alott of loot

You will need some information for acceleration fuel.

 

Although this information can be generated also from manifold pressure

I found this result not that good like the TPS signal.

 

There is a bit of hesitation because the TPS gives the signal just when the throttle

plate moves, where the MAP is a reaction on that a bit later.

As it is pulsing a little bit it must have a larger distance to start work

because else the accel clogs in under some normal driving situations.

 

So the EFI has to wait some milliseconds until from MAP signal it becomes clear

what driver is doing and may need fuel shot or is only driving under critical situation

where only some pressure pulses are generated.

 

Did you bring EFI to work properly with MAP generated accel fuel and what was your trick?

What was the cam that was in use?

Hi all,

New to this forum and have been reading all your posts on efi, would love to do this on my TR6, its a PI at the moment. Loads to think about and questions to ask. Hear is a few

1. Which injection system do you run ,sequential semi sequential or batch.

2. Has the slow running on single throttle body been achieved i.e. Traffic

3. Injector size in cc.

4. When you have removed the distributor, what keeps oil pump shaft in place.

Cheers Phil

1. Which injection system do you run ,sequential semi sequential or batch.

Does not matter for our cars, I started with a Megasquirt1 that does offer only

two batches what was fully okay.

2. Has the slow running on single throttle body been achieved i.e. Traffic

?

3. Injector size in cc.

The Opel Omega V6 2500 injectors are okay for that, I have the BMW 320 in use

4. When you have removed the distributor, what keeps oil pump shaft in place.

It is necessary to have the adaptor hold down by the two 5/!6 bolts still in place.

The carb version is smaller and can be plugged with an aluminium plug quickly made on a lathe.

 

I would start with one thing, either fuel injection or ignition timing and extend later.

Makes life easier.

You may find this page helpfull, does not matter that it is for a 2000

Which do I go with microsquirt or megasquirt or does it not matter

Can you swap these from car to car and just change the programming to accommodate different engine and number of cylinders.

I see you have kept the butterflies and not gone for single TB any reason or just preference.

I'm no EFI expert but if you have a single throttle and you get an air leak, quite possible if using the existing plenum pipes, the engine might rev to destruction.

Hi Phil,

micro is as the name says very small, good for bikes.

Has due to limited space not all on board especially the

MAP sensor is not included.

All is build ready to work because its SMD technique and

would be difficult to solder at home..

 

MegaSquirt is bigger and normally delivered in parts to be soldered by yourself.

It can be adapted to nearly every engine and every mode to measure the air

what is the base to meter the correct fuel.

We have speed-density, alpha-n and MAF sensor.

It can also control the ignition.

 

Single plenum needs no sync but is limited to smoother cams.

My persomal limit is the 280 degree cam like CP-PI had.

Some got these cams run very well with single body.

 

With hotter cams each plate for every manifold runner is the way to go

like motorbikes or sporty engines like BMW M3 have.

Throttle response is a bit more crispy.

 

This is a nice shop

MS2 with the 3.0 board, sensors for water and air temp, a TPS sensor

and the stim to test would be a comfortable solution for the TR6

MS1 with 2.2 board is cheap but a little bit out of date.

Yes..one intake backfire....and only an ignition switch that also locks the steering to kill the engine.

Every Megasquirt has an adjustable rev limiter.

May cut ignition or fuel or both, hard or soft limiter

MS2 also has the provision to take engine temp into account

not to let cold engine rev higher than healthy.

 

-So just lean back if throttle locks, roll to the side and take

your time to switch engine off when its convenient.-

 

By the way, for safety reasons it has a fuel cut off when engine is not running

[Noswal]

So if I purchased a used ms2 v3 I could wipe it clean and start again with new parameters for my engine

Sorry if I'm asking obvious questions, I need to find all the facts beforehand.

[TriumphV8]

Yes, that is possible but it will help to get somewhat deeper

into the EFI theory. It helps a lot not to ask many questions

later when setting the engine data.

 

If you buy a second hand item it is still a good idea to buy a stim.

It simulates the engine to the EFI and with the Laptop and Tunderstudio software

you can try out all the things at home without spoiling the engine.
