Hi Adrian, First of all, I would agree with Andy's earlier comments and would just like to pass on my experience and opinion on the ECU change. I can't comment on a knock sensor. Up until July this year I had a standard Morgan system on my 3.9 hotwire 97+8, ie ECU, air filter, manifolds, cat and exhaust. I was not 100% happy with the general running and acceleration and it was suggested (by someone I have great respect for) that the Tornado chip would help to improve this but wouldn't give any extra BHP or MPG. I decided to go ahead and had the chip replaced, the result was a definite improvement with a smoother tick over and a noticeable improvement to the acceleration in the lower rev range. I have no hard facts to back this up, but this is my perception and I should also add that SWMBO commented on the better sound of the exhaust on my return from having it fitted. When the chip was being fitted and checked out on the diagnostic system it was noticed that one of my injectors was functioning slightly below par but it was nothing significant to worry about. However as we was about to go on a tour of the Italian lakes within two weeks I decided to replace all the lucas injectors with bosch ones. I believe that this improved the smooth running even more and slightly improved the MPG. I should hasten to add that the my consumption has improved by about 1 MPG which wouldn't justify the cost of replacing injectors alone. We clocked 2.8K miles during our tour of the Italian lakes and the overall consumption worked out to be 28.4 MPG. I am now extremely happy with the performance and don't plan to make any further changes in the future other than where it's absolutely necessary. Incidentally, because there has been no increase in the BHP with this upgrade, my insurance has remained the same. As to the question "was it worth it"? That is very subject, but to me it was. Hope this has been of some help to you. Regards, Allen

To my 96 3.9L +8 I have fitted librands twin stainless exhausts and manifolds, and a K&N filter this has improved performance but I understand the engine can run a little lean plus the torque curve can be improved with an ECU CHIP change, either Optimax or Tornado. Also I believe that Vauxhall knock sensors can be fitted that turn 90 degrees and clear the new manifolds. Can anyone tell me their experiences with either chips and/or knock sensor and what you think. Is it worth it, impact or improvement on fuel etc. Regards, Adrian Sent from my iPad ------------------------------------------- View posts on The Mail Archive http://www.mail-archive.com/[email protected]/ [http://www.mail-archive.com/[email protected]/] Modify Your Subscription: https://www.listbox.com/member/?&; Powered by Listbox: http://www.listbox.com ----- No virus found in this message.
