To understand better how it works you must understand that, although your engine needs to run at varying rpm, it also has an extra factor to be considered - Engine Load. This can be considered as the difference between part-throttle cruising or full-throttle accelerating or pulling. When you are on part-throttle cruise driving mode, with Optimax or Tornado the fuel mixture will run slightly lean, giving you the best possible economy. As you demand higher & higher load performance, such as under hard acceleration and load pulling, the Optimax and Tornado will allow it to run richer, and give you the best possible performance both without losing sight of efficiency.
With over 120 load/rpm adjustments, the Optimax and Tornado are streets ahead of any competition. (most of which just target more bhp with more fuel dumped in at high rpm). As an essential basic upgrade for engine economy and efficiency. When converting to a large capacity and/or performance tuning.Lowering engine temperature & avoiding block cracking. As there are also a few variations of this ECU type, we will need to know what family type yours is. All Rover V8 Hotwire type systems need re-chipping, especially with any engine changes, upgrades, or engine swap outs. Apart from the obvious gains as detailed above, any engine upgrades you use on the Hotwire Engine will gain you nothing without having the appropriate fuel map changes.
Even something as simple as a K&N filter upgrade will further strain the engine's fueling, and losses are more likely than gains. Please do not Confuse Optimax & Tornado Chips with inferior products seeking only bigger numbers (BHP) at the high rpm range, and sacrificing important low-end and mid-range power, as this is where 98% of fast road and cruise driving is occurring. Whatever the reason, re-chipping should be treated as essential for all capacity or performance upgrades when made to the 3.9 / 4.2. Apart from the obvious need to re-chip your ECU when increasing engine capacity, the following are some of the superb advantages obtainable.The Chip that controls the engine's fuel map is easily located and replaced. The Optimax or Tornado chips will add substantial increases in economy, throttle response and pulling power to your vehicle, and in most cases are the ideal upgrade. If, however, your needs are for ultimate power (without losing sight of efficiency) then the Tornado ECU chip would be more suitable.
Whichever one you choose, you are going to be pleasantly surprised by the huge gains achieved by such a quick and simple upgrade. No matter how good your engineer or local garage, there is no way the best can be got from your engine unless the ECU fuel map is considered and changed to suit. Chip Identification and replacement details.
All the following information assumes you have the Hot Wire injection system. Please check if your ECU type is 14CU, or 14CUX (14CU is normally American export only and currently cannot be chipped) To be able to supply the correct family of chip we will need to know some information from inside the ECU itself. Inside there is a small chip with MVA on it. We need to know the rest of the numbers and letter.
Fully Tested for almost all V8 engine needs. Our Tornado & Optimax ECU Chips have been extensively developed on vehicles under exacting Rolling Road conditions, thus ensuring perfect fueling throughout the rev range of almost any V8 Engine, and should be seriously considered as an important part of your vehicle's needs. The following are just a few advantages and adjustments you can expect to have gone into all our ECU Chip upgrades.
Engine Temperature Map: Decreased cold and warm up fueling to reduce the risk of flooding. Throttle Response: Quicker throttle response. Airflow Meter Scaling: Vital for good drivability and fuel economy, especially on large capacity engines. Allows correct control of part throttle fueling.
Re-profiled Fuel Map: Provides good fuel economy on part throttle, and allows engine to rev more freely, (standard profile reduces fueling heavily after 4000rpm). Idle Speed: Lifted to give smoother idle. Throttle overrun braking: Increased engine braking. Removal of road speed limit: Standard 113mph road speed limit removed (Range Rover only).K of flooding, starting delay to allow oil pressure to build before starting. Non catalyst, catalytic converter type, Dual tune versions as standard. Which chip should I go for? 3.5 engines standard or mildly tuned. 3.9 engines standard or mildly tuned.
4.2 standard or modified. 4.6 5.0 or other Highest specification engine.
