Well I have cosworth m2 cams, and the rice in me wants to hear a little lope. As well i am sick of my car cold start up idling at 2,000rpm.. So far heres what ive done,

RPM:

*C RPM

-32 1664.06
-8 1500
7 1398.44
20 1242.19
34 898.438
50 882.812
77 851.562
82 851.562

although after doing so it still idles around 1000/1200 rpm with engine temp at normal operating temp.

and my mivec map is:

From 500 rpm / 1250 10 / 50 load is it all set at 14.4 * still nothing. no lope or anything. My actual timing from 500 / 1000 rpm 0/50 load is all at 3*

Am I missing something? Ive searched many times on this and found people can get their car with bigger cams and mivec to lope like it should. I'd think my cosworth m2 (272s) would have some lope in them?

If someone could guide me in the right path that would be great. Some suggestions even would help me try to get this down.

Thanks,

Tyler

 

Subscribed. I'm not cam'd but my car does the same. My tables are set to go to 800 at operating temp, but always stayed around 1300-ish. We did get it to go down a little and there's a way to do it in EvoScan to set your idle. You turn that on, and then adjust the screw on the top of your TB.

 

^^ correct. I would set the biss screw with evoscan first and do a boost leak test make sure u have no leaks..

 

Yeah, I was seeing if i can without evoscan. I dont have evoscan.

 

Don't touch the BISS screw if it's still at it's stock position. The ISCV tables are what you need to adjust. That's what gives you your idle rpm. The desired idle rpm table is more of a"guideline" for the ECU in my experience.

 

Bump that helped get idle down to 800/900!

Still no lope :/

 

Should definitely lope at that rpm with that low timing and as much MIVEC advance as you have...

Have you confirmed with evoscan that your MIVEC and timing changes are taking effect?

 

I dont have evoscan.

 

I dont have evoscan.

 

Do you have a Tactrix cable?

 

Yes

 

Then you should have evoscan
