Alter Crank Signal`

[buffetw]

Looking for MC to be able to alter 58x degree crank signal to 24x crank signal. Possibly build another device to work in opposite direction too.
Does anyone know how? Willing to pay for expertise. thanks!

you are looking for something that even bosch engineers cant create

why do you think that this is impossible?

[sherl645]

Why do you need to do this?

i guess that buffetw is changing ecu on vehicle with one number of pulses, with another ecu which needs another number of pulses....

The only device that will work is a 24 tooth crankshaft wheel

why do you think that this is impossible?

58:24=2.41666666666666666667

Do you have the ability to write the code to make this ecu work with some sort of a signal divider\multiplier?
What about the missing tooth????/??

Have you ever been working with standalone engine management systems?

If it is for use with an after-market ecu, than it's a very crappy ecu. Most decent after-market ecu's will allow you to use a 60-2 crank signal.
I ferequently convert car's to 60-2 when using Motec, just to name one.

@ dimitar, guy already has solution that he used before, he wants something cheaper, so don't say it's impossible...

They've have 100's fail in the Aussie heat.
It is for a Delphi ecm.
Inductive pickup.

Lingenfelter also makes some PWM devices that defeat traction control events that could be easily made.
I'm have a theory Bob Bailey, ex gm engineer/calibrator is designing the devices.

*CONFUSED*

Could you get a pelfier element and make it cool the crank sensor you have already?

sorry for confusion.

the current product that is sold in a potted electronics box is burning up due to heat. I'm trying to reverse engineer this box to create a better one that is more durable.

IM not saying its impossible but it would be pain in the ass to make it work. I have been working a lot with haltec,motec,megasquirt,emerald EFI systems which are quite annoying when it comes to crank signal processing . They all have bugs and are very sensitive on crankshaft sensor signal.OEM ecus are not better either but the manufacturers overcome this problem with a lot of tests and experiments.A bad ground , bad spark plug, faulty plug cable........etc. can make the RPMs float around plus the crank signal modification make things worse.

buffetw, could you measure maximum pp voltage on that crank sensor that gives 58 impulses? On high revs that is....
I don't know whats in that box, but, bidirectional TVS diode(between signal wire and ground) could be solution to your problem....
I really can't see any reason to have something that would overheat inside...it's not driving any actuator or something like that....
Some of those crank sensors produce high voltage when on high revs(24V pp ac is normal on idle) even 100v is possible.
Maybe that's burning your electronics.
You could easily limit voltage to desired value with tvs diode.
