Re-Chipping with RPi chip

Hi all, I recently stumbled across (found in another post) the RPi site in England and am very impressed with what they say. Being a geekish type, I am intrigued by the re-chip for the NAS V8 they offer, and before I plunk down the $400 ish to obtain one, was interested in knowing if anyone else had purchased one (or know of anyone who had) and what the general consensus was. As always, thank in advance for the insight!

Neo, I will let you know in about a week and a half. I ordered a chip thru Rover Connection and will send my ECU to them mid-next week. Should have it back and installed the first of the following week.

I doubt that re-chipping a stock engine will make any difference in power and especially if it's N/A, MPG maybe but not power. Let us know if you noticed any power increase.

Good luck

Yousef, I fully realize I am taking a chance with the chip as most comments I have read do not seem to think I will get much out of it. But I used a chip years ago on a stock BMW 528e I owned, which was a dog on acceleration, and the chip made just enough difference that around town driving was tollerable. No, it was not fast by any means, but it did put me higher on the power curve enough to be worth the money. So, again, I am taking a chance. But hope for the best.
Rick

Thanks for the feedback. I look forward to hearing about your experience Rick. I persoanlly, am not as interested in the power aspect, but the potential/touted longevity improvement. The way RPi described it on thier page, the Rover V8 runs pretty lean from the start. They indicate the chip will actually enrich the mixture. My suspicion is this might actually degrade fuel economy, at the gain of cooler exhaust valves = longer life. Just curious. Power is always nice, but I am looking to improve MTBF (mean time between failure!). Thanks again guys! By the way, what is the conference I have seen referenced?

I wouldnt go for it - if it enriches it almost certainly means more fuel consumption. I would have thught. Don't believe all Chris Crane at Rpi claims - I had his Mallory ignition set up and it was a POS. only resolved by putting a solid state pertronix unit in. Their engines are basically good but he doesnt always know what he is talking about.

As I said, I know I am taking a chance but because of my prior experience with chipping, I am willing to do that. My main goal is a little more zip around town, which is how I use my Defender 90% of the time.
For those interested, I will give my feedback.
Rick

Rick, have you tried Hypertech (spelling). Those guys make some nice programmers. Those things work great especially if you have any auto. up to 25 hp increase!

i think you would have to have omse kinda forced induction to get that increase outta a rover .or some other variaty of something? IMHO bolt on stuff dont do too much, i know a few folks that have got the power programmer (hypertech) it was effective given that its a kinda small motor in a chunky truck well go figure. If I had to make that pile of rover faster I would take it to a place that builds performace stuff for drag racers etc, headwork etc etc. more air+more fuel=bigger explosion=power? If i was rich I would spray a healthy shot of juice into the intake I am sure that would be fun


what are the supercharged D-90 owners saying?

I agree that to really get a power increase, one would need to make more substantial modifications to the engine.....or replace it. I am a hot rodder in my "other" life and we are currently putting a Corvette LS-1 in my 57 Chevy pickup to get it down the road a little faster. And I have talked to my rodder friends about my D-90 and we may try some things, nothing definitely planned as yet, in the future to get more power. Or I may change out the engine eventually. But until the 57 is finished, I can't see doing that. ($$$)
So, until I can tackle more, I am just trying to get a more pleasurable drive around town, again, with a little more zip. I hope I get it with this chip.
Rick

How much is the Hypertech?

After I put on the 33" it was a dog, I super charged mine 6 months ago. WOW, what a difference. I have no problem up hills. Before I was in 4th going up hills, maybe 60 mph. Now I have NO problem acelerating up them. Also no problem bouncing it off the governor.

Talking

Hey guys, I am a little confused. I looked up the Hypertech power programmer and chip and don't see a Rover application. Is there something I am missing? Yea, superchargers are cool!

Did you try calling them to see if they can make any?

Quimbola,
I have read so much about the superchargers being so bad for these engines.....did you do some research on this? East Coast Rover speaks about the bad points of doing this on their site, as does RPI, I believe. But I am intrigued by this option. I know hot rodders supercharge engines all of the time.
What was the cost?
Rick

I would agree that superchargers are cool and they do lay down some hp, but in my opinion the 4.6 is the better deal.

My 4.6 long block engine will make a little less hp, but for close to the price of a supercharger I have a brand new engine. I had 130,000 miles so a supercharger wasn't for me. If you really want hp, go for the 4.6 pursuit 2.

Matt
