Re: Looking for infos

Is it possible to use a 16-1 trigger wheel too? From 16 to 200,right? N-1 or N-2 only?

Yes, right.

Re: Looking for infos

Hello.
Thank you very much.
I'm trying to use the forum in a better way too.

You can not achieve good dwell time with it (it will be very hot on idling).


That was suggested by my instinct too whan I was thinking of that ignition module.
I'm studying the injection too,I have a lot of question... Sorry!
While I was looking for infos I think you've just added that new module.



At the moment I'm not going to ask about it, I'm still watching wiring diagrams of singlepoint and multipoint...
Thanks in advance, be patient,please.
Bye.

Re: Looking for infos

Hello.
We need two modules for multipoint injection.





At the beginning I watched at the wires of diagrmam only, then I realized that there were the note too.



IGN_OUT 3 and 4 for stepper motor module, FE and IE for INJ_OUT 1 and 2

What does mean * in case of IE?
The parts from the shop :

4 channel driver for high impedance injectors.



What about the stepper motor module? Is it the same module for automatic choke control unit?



Thank you very much.
Bye.

Re: Looking for infos

Hi,

We need two modules for multipoint injection.

For 8 cylinder engine we need 2 of these modules. For 4 cylinder engine we need single module. This module has 4 channels.

At the beginning I watched at the wires of diagrmam only, then I realized that there were the note too.

Yes, pay attention on notes.

What does mean * in case of IE?

This means than in this example you need to remap IE output for INJ_OUT2 only in case of semi-sequential injection.
For simultaneous injection we need only one output (because all injectors fire simultaneously, all 4 inputs of module connected to single output).

What about the stepper motor module? Is it the same module for automatic choke control unit?

Yes it is the same and can be used either for IAC or automatic choke control.

Re: Looking for infos

Hello.
Thank you very much.
Sorry for the confusion, when I said two modules I didn't men two injectors drive boards. I meant a module for injectors and one for IAC.
However your explication made me understand better the next things.
Now it's time for singlepoint injection.
It takes just a module for injectror and IAC.

The same output for injection as for not semisequential multipont .
That module is good for singlepoint or not semisequential multipoint.
The output for IAC is diffrent,now it's ECF.
Why are there two wires only for IAC and one is optional?
I think that module is good for a injector or four injectors only, not suitable for two or three injectors,right?
I think so because there is a four channel P&H injector driver even if I don't understand why.
Thank you very much.
Bye.

Re: Looking for infos

This unit can drive one low resistance injector or 1-2 high resistance injectors (this is because hold current of 1A is not sufficient for 3-4 injectors).

Re: Looking for infos

Hello.
That's the T.P.S I posted time ago.
I didn't realize that isn't good to use as a load engine senor.
I'm in trouble to post on this forum because a technical problem.
I don't know how and why.
This time I'm trying again to post.
I had to "switch mobile style" to see the tool to post.
Thank you very much.
Bye

Re: Looking for infos

TPS is not bad as load sensor. In some cases it is only reasonable solution, e.g. if intake chamber is too low and pressure pulsations are big.
TPS must generate linear voltage output, output voltage depends on position of throttle. If your TPS has only on/off switches and has no variable resistance part, then it can not be used as load source.

Re: Looking for infos

Hello.
Thank you very much.
Do you mean the socalled Alpha/N referred to the TPS used as load sensor?
I understood, it takes a potentiometer for that.
I didn't know that there were TPS missing it.
I've just seen three different TPS.
The linear voltage output is represented by an arrow in the schemas.
There are TPS with more pins than three.
