Look at the powercommander from dynojet.com or powercommander.com
It is a 3D mappable fuel and ignition intercepter piggyback for high rpm motor cycles.
On my 96 Impala SS the colors are tan, signal low. Purple, O2 signal. Pink, 12V supply for heating element from underhood electrical center. Black, ground for heater circuit. Your's is most likely like Patdaly already suggests.
To understand what you are going to measure read, for instance...
My theory is that those claims may be based on thruth, if you're lucky, like with many miracle solutions(!).
I suppose that if you do not cool the gases on the way to the next join, they have more volume (more heat is more volume). Thus the timing and duration of a gas pulse that aids...
Checked the price with the VW dealer, 154 Euros(!). Saw the best price on the net in the USA for $28.99 (!) What a rip-off. Unfortunately it isn't worth buying it there if you only need 2 or so.

You're right, I misread that, probably because we express economy here in liters per 100 km, so if the number lowers then economy improves, stupid mistake of me. The Bosch book on Diesel engine Management draws a curve of fuel consumption that decreases, may it be minimally (1%)at...
From my point of view these trials can create the wrong impression if there are no other changes made to the system.
It is a bit like the story with the special spark plug cables being superior to OEM cables, ignition coils with more power, sparkplugs with more or less gap, different materials...
Well, if you read this long term test report then it appears that EGR can improve mileage: http://fleetowner.com/ar/fleet_bowman_reports_egr/
It seems that the only thing that is certain is that the NOx is reduced, if that compensates the increase in particle count and ppm HC will have to be...
As an 'ex' senior engineer/manager for a reasonably sized ship repair company and over 30 years of working experience I would like to comment that ISO 9001 has nothing to do with engineers, a company without engineers can also be ISO 9001 accredited, in theory even a one man company can. It has...
Gentech,
Looking at some catalogs on belt drives I wouldn't jump to conclusions based on the above at this stage. You may just have the wrong belt spec. with regards to type of reinforcement. I would contact people like gates.com and let them ask the right questions and see what they can come...
Another point to think about.
If the unit gets started often and if the generator starts running up to operational rpm directly, as some do, then there might be a lot more torque than the belts are calculated for during the startup. In this case maybe you should try V belts instead allowing for...
There is an article of 1997 on this subject on http://www.damek.kth.se/~borje/Artiklar/SAE%20982476.pdf
For normally aspirated engines the temperature story also follows those lines, nevertheless EGR is not normally used at WOT when the temperatures are usually at their highest.
EGR is also...
Zimbali,
I believe we are straying from the original question: chiptuning, which I would prefer to call re-programming of ignition and a/f ratios, in the closed loop area and beyond, how it works and what results to expect. I believe the question has been answered.
Yes, in general NOx...
About Cat temperatures and A/F ratio.
Well, I thought this was an engineering forum..
For information directly available on the web read http://www.randomtechnology.com/technical.html
For other, even more authoritive, publicized info about his subject read for instance 'Gasoline Engine...
Marine paints and their application is a dynamic topic, new environmental laws and solutions by paint manufacturers are constantly changing things. It has been a few years since I was involved in newbuilding of supply vessels and VLCC's but the best way it to consult people like Hempel, Jotun...
I don't know what they mean by best emission, it is well documented that emissions get worse as you move further away from lambda 1 (14.7:1). I own a couple of chevys as only reference for american cars I tuned, and they didn't have lambda control as it was not needed in the country I bought...
I suppose the supporting hardware was bad in your case. Dynojet uses the LSU4 sensor, they work excellent in the area you have to work, from 10:1 to 28:1. Use it everyday to performance tune cars. I am not an electronic engineer so can't tell you how to make the supporting hardware but the...
