EGR Block on CRD Patrol

[azzacalabaza]

Ok. I guess I just need to install it an see what happens. Hopefully I don't get boosting problems. My exhaust size is standard so maybe people get different results with other mods.

As for chipping it. Is there a chip that improves fuel efficiency? If so, what do you recommend and how hard is it to DIY? (like for a dumb person )

I had no issues with a full egr block and stock exhaust.
Disconnect the battery while you do the mod and it'll reset the ecu.
Not sure if they relearn things but yea I had no issues..

Only had issues since 3" exhaust has gone on..

Thanks bigguwesty. Seems the 3" upgrade throws things out of wack.

Hey azza sorry for the late reply yeah I did the Maf sensor and disconnected the battery I was getting about 500 kays out of the main tank after the block,and roughly 600 before. I just installed Dawes valve set up( thanks mudski) and put a 3 inch DEA system on in the last few weekends, I went camping last night and did some driving around and so for I have gotten 650 from the main and still have a bit under a quarter of a main tank left��

I had just the block as the sole mod and had it that way for about 7 months, I have the cheapo EDS from 4wd supa centre to clear the codes, it wasn't till I installed a boost gauge that I noticed how bad the spikes were on the freeway between 22-8psi,

Thanks matty. I only have the scanguage at the moment to monitor boost levels. I thought the dawes setup wasnt needed on the CRD patrols?

[BigRAWesty]

You won't need boost control if your just doing egr.
The ecu handles that ok..
Again it's just the exhaust which brings out some issues

[azzacalabaza]

Awesome. Will post results once I get it done.

I'll disagree with westy there in my instance I defiantly needed some form of boost control with just blocking the EGR mine really didn't like it, the boost spikes were before I did the exhaust and the ECU did a lousy job with the boost control especially at cruising speed, i never got limp mode but I personally think the runs better with boost control.

Yea agree it's better with boost control.
I could feel it surging in the higher gears.
But I never saw above 15 psi on the scangauge.
I did disconnect the battery for the hour or so while doing it..
Wether that has affected the ecu and it's relearnt it's new perameters I'm not sure..
