Thread: Remapping EU2 motors - a word of warning

I recently got a Bruce Davis remap on my 2004 D2 and am pretty impressed. More power througout the rev range with a dramatic increase above 2500rpm (where before there was almost no power gain and seemed to rev unnesessarily for no gain above 2800). Good service and good knowledge, fuel consumption is slightly better but now has a whistle from the exhaust?

Maybe you could just ask Bruce to modify the map to your specifications.

Glad you have had a good experience. What you are describing is pretty much sums up what I dislike about the Davis chip. I'm looking for better balance and distribution through the rev range, rather than buckets of power above 2500rpm.

They all like it till they get offroad and try to technical drive something and get.......nothing then.............................Wham.....

I have a Davis chip (2004 D2a manual) and find I now have "buckets" of power over 1500 compared to the OEM version and better at take off (say 1000RPM). I don't think there's any chip that's going to give a huge improvement until the turbo spools up but i'd love to know of one. The OEM version seemed completely gutless till 1700RPM which the Davis chip has reduced to 1500.

I have several friends with Hiluxs, which don't seem to have the apparent turbo lag our Discos have. Why is that? Surely not just the low end gearing?

Luxs have VNT / VVT

Drop a VNT on a TD5, map it and smile

Before anyone else wastes their money - that is the wrong connector, as I've just discovered.

It's wrong width overall, the pin spacing is wrong, and the housing doesn't have the cutout which would allow the plug to mate with the pins even if other 2 factors were right. In other words wrong, wrong, wrong.


This one looks more like it but I'll try to confirm before randomly ordering product:

At least the keying on the body looks correct, so that is a start.

ADD:

The above product (Metri-Pack 150 Pull to Seat) is being phased out by Delphi, but they have introduced a more modern replacement part using more conventional push to seat design which will mate with the 4 pin AAP sensor. The replacement is showing up in searches as a Harley Davidson part. At this stage I haven't found a source I'd actually place an order with.

ADD2:

In the end I had to order the Metri-Pack 150 as I wasn't able to find a trustworthy source that didn't have a MOQ of 380 units.

I got mine from here:
http://www.bmotorsports.com/shop/pro...roducts_id/836

Ended up being $18 by the time shipping and low order fees were added in.

These "pull to seat" connectors require passing the wire through the connector, adding the crimp connector, then pulling the connector back into the housing to seat.

Thanks Paul I was wondering if I had the wrong plug or sensor


Roger

Definitely a case of the wrong plug.

I thought I'd try a 5mm vacuum connector cap on the EGR outlet. I'm not sure it's the best solution but I'm going to have trouble removing without cutting off so it's probably ok.
