TUNERS; 15-17 IMRC control

[WildHorse]

For the tuners here;

Seems after a 5th revision, the guy who was tuning my car at VMP was fired, and left me high and dry with a crap tune. Crazy amount of clutch protection, idle timing ATDC, erratic idle, etc. Anyways, long story short, I had to revert to a pre IMRC delete (cause I went with a 18+ intake manifold) tune just to get the car to run well. So if you guys could indulge me i have a few questions, since i'm running the intake and the CEL is showing the typical IMRC out of range/not functioning p-codes. My tuning device allowed me to raise the RPM limit, 2-4k ignition timing, 4-7k ignition timing, and GLOBAL timing, MAF percentage so;

1. At what RPM does the IMRC goes full open ?
2. What other compensating factors is required when going IMRC delete? ignition timing ? Cam timing ? Both ?
3. Is it ok to run 'as is' for now? There's just some slight bucking under 2000 rpm, and sometimes it stalls when coming to a stop.

Thanks in advance

It’s not that simple. It’s open at map 14 and a given load looks like this and a lot more

Don't you just tick IMRC CLOSED and copy everything from IMRC OPEN to IMRC CLOSED ?

If you have the software yes

Do you have a Diablo device handy?

Yes Sir.

 

[MKL_DS]

Yes Sir.

I’ll get you something that should work well on Monday. PM me a full mod list and I’ll give you my email.

Come to find out, this is the incorrect way of doing it.

 

[K4fxd]

Ford does it one way, Roush another and Whipple yet another way.

Ford does it one way, Roush another and Whipple yet another way.

And all three do it better than you.

Shoulda just gone with Lund...

Went with Diablosport/Holley. There canned tunes will rival LUNDS in overall power & drivability.
