Starting New Engine For First Time....on A Base Map With New Cams

[Mad Scientist 106]

OK here's the problem.

 

I will shortly (with a bit of luck) be wanting to get my new engine running for the first time. The problem is, it will only have a base map on the (probably Omex) ECU prior to mapping. Aswel as this, it has new Catcams fitted so............

 

I need to start it up and run at 2k for 20 mins or so to run the cams in properly, but I suspect it won't run very well on the base map. The rough spec. is a GTi6 head on an S16 iron block, with 2.1 diesel crank and the catcams.

 

What's the best way to get around the issue?

 

I don't really want to delay first start up until the mapping session incase there are any niggles to sort out.

 

How have others dealt with this?

 

How well will the lump run on a base map?

 

Is there a risk of bore washing etc. due to innacurate fuelling whilst running the cams in on a base map..............

 

All comments appreciated.

 

Thanks,

 

Pete

Have you got a wideband lambda? And does the Omex support closed loop fuelling?

[Mad Scientist 106]

I had planned to get a wideband and, a quick look at the Omex site later, I think the 600 series ecu does support closed loop fuelling.

[Tom Fenton 1,542]

In that case you can see the fuelling with the wideband, and the Omex should be able to control to a reasonable level to allow you to do the 20 min at 2k revs. Just keep a careful eye on the water temp whilst you do this.

Sounds simple enough I suppose. I guess a lot is going to be to do with the base map. I suppose worst case if there is an issue, just shut it all down, adjust the map and start again.

 

Anyone else got any advice to add?

 

Thanks for the help so far.

Unfortunately I don't know the Omex software so can't really give you any more pointers. If it was Emerald or DTA I could tell you how to go about it.

The most important thing is to run the cams in properly for 20mins. The mixtures really aren't that important as there will be no load on the engine. As long as it's running nicely at 2000 don't be too concerned. Adjust the mixtures on the go. Don't let it idle. If it springs a water leak, shut it down, fix the leak, then go back to 2000 and finish the 20 mins. Also make sure you use a break in lube such as made by Crane or Compcams.

Peter what about using Red Line assembly lube?

Any good ?

It sounds ok, but doesn't specifically mention zinc which is the key ingrediant. I use the other two like an assembly lube, then pour the remaining contents over the cam(s) before fitting the cam cover.

Thanks Peter. Am just in the process of sourcing some assembly compounds so thanks for the tips.

 

By the way, did you get my PM regarding the exhaust wedge?

 

Thanks,
