Spark issues with Calvin's car / wasted spark chit-chat

Anyone done a conversion to Wasted Spark on LH 2.4 ?

@calvintibia001‌ I haven't done one, but I studied it pretty extensively when I was thinking of doing it on the 740. What did you want to know?

Can you actually do it on any LH2.4 EZKs ? And I have little confidence on opening up the EZK and soldering shit

The car got some ignition problem, pretty sure is Dizzy / Coil, I am thinking of going Wasted Spark since I am replacing the ignition stuff, and it should cost around the same ?

its worth getting the car running properly first

there isnt much to go wrong in an LH2.4 dizzy or coil

If Wasted Spark can be used on NA EZK, I want to test fit it on NA setup and then just resolder that onto the Turbo EZK

if the issue dosnt lie within the parts you replace, itll run like arse on wasted spark too

This + however many is 'a lot' these days.
I'd work on diagnosing and pinpointing the issues that you're experiencing as the very first thing to do and then think about whats next once you have it sorted out.
Otherwise, you will find yourself chasing your tail.

So you telling me when i check the distributor, there is a literally no spark from the Distributor and a very weak spark from the coil, and that is not ignition related ?

Vee_Que

How are the leads? The distributor on them doesn't so anything except provide spark from the coil. If the coil is weak and you can prove that then fine. But I usually find its a lead related issue. Is it still leaking as well?

Calvin what parts have you replaced?

Well, one of the spark plugs boot was split, so i got a set off a 850 just to test it, same problem

nickm;29773 wroteCalvin what parts have you replaced?

Replace the Coil Wire and Spark Plug Wire, both are off a 850, but they look brand new.
And replaced the Spark Plugs wif BPR7ES

Have you tried another coil?

Nope

coil and power stage would be suspects.

I was goina replace the Coil and the Dizzy, but I think swapping to Wasted Spark won't cost a lot more

nickm

in the purple circle!

Seems like a lot of possibilities

Could we get this stuff moved to a "Calvin's car runs like crap" thread? It's going to make it much easier for us to read and respond.
