Help for ignition map needed

[Happy Dane 1]

I am changing my tired tu3 engine for a fully rebuild Tu5jp4 engine. 

I am using a standalone Ecu as My attept of using the original cracked Bosch failed. But I Would love if Any have a timing map to share. I need just a startup. The engine is with standard camshaft, but without cat and restricted airfilter.. 

Thanks

which ECU?

[Happy Dane 1]

Sorry for the delay. I am using a Ecu from Racing electronic. Its controlled by Tunerstudio like microsquirt.. I am using the VW coils, and a fly by wire control to handle the trottle.

This one..

Start with 5° to 10° BTDC @ idle and ramp to 20 °BTDC @ WOT @ 6500 RPM. That should be at least sufficient to have it rolling.

Is the ignition mapped via TPS or MAP sensor?

 

Here's a typical safe map for a 16V engine mapped via manifold pressure (MAP).

I am using Map sensor. Thanks a lot! Will do the wiring and startup during x-mas..

The position of the lambda sensor is questionable to say the least. Better relocate that to where the 4 pipes are joined.

[welshpug 1,621]

definitely agree with Thijs there, that will not give you a consistent reading, unless you plan to add another 3...

I have relocated the lampda. Agreed but the bosch system needed 2 lampda. I have changed to a standalone Ecu and is making the New wiring, incl a fly by wire unit..

The timing map ends by 5000 rpm. Is it the end of avance, as I plan to use a lot higher rpm? 

[petert 549]

Use the same values from 5000 onwards until you get it tuned.

[welshpug 1,621]

would say that 5k is more than enough until your mapper gets hold of it.

Thanks a lot.. Here in Denmark there is No Welspug, or another genius that can do it right.. I am on My own.. 

Have a lot of experience in tuning carb engine.. 

Thanks and Best regards.. 

By the way.. Happy New year

There’s not really any other way than to map it on a rolling road. At best you are sacrificing power. At worst you can damage the engine.

Setting up WOT ignition angles isn't all that difficult with some det cans and time. It is the low load areas of the map that you will need a decently braked dyno for.

 

Is that a wide band lambda sensor you are using?

[welshpug 1,621]

definitely get it on a rolling road, anyone familiar with that ecu can do it, they don't absolutely necessarily need to know their way around a modified Peugeot.

I am using a wideband lampda, and fly by wire conversion. The Ecu uses tunerstudio, and I have used a lot of hours reading how to setup. I can find a rolling road, when its running and is solid.. 

[Happy Dane 1]

Still fighting the fly by wire setup.. Oh dear.. Its a nightmare.. Takes too much time

[Happy Dane 1]

Engine is running fine now.. Did throw the fly by wire over the shoulder, and did fit a old school throttlebody. Stil playing with tunerstudio, but a great swap, instead of the tu 3 engine.. Will find a rolling road in Denmark, but it sounds realy strong. Thanks for All your help..
