mark adams chip

[daz the plumber]

been offered a used standard 4l mark adams tornado chip , i was wondering if i could fit the chip , then book it in for a re map , do you think that would be ok . i have free access to a rolling road , my mate could see if there is any improvement on the standard chip .he`s been through the car and he thinks the combination of the induction , trumpets and cam is a little to much for the fueling map .

In my experience those subtle mods shouldnt be too much for the lucas to cope with, the system seems very good at scaling up the fuelling in line with airflow increases. However, as greenv8s said on your other thread, youre asking the wrong people. Unless your friend is a lucas expert ask mark adams!

mines got all those mods and runs sweet as a nut and 260bhp to boot, and yes its a 4 ltr and not been chipped

too many and's there i think

so, why do people spend the £420 on a chip .i was trying to save a few quid , stick it on ,see if there is any improvement and if not pay for the rr session , i have saved £300 on the price of the chip .it might even work better with the tornado standard chip .

I think i can see where your coming from, the chip does improve fueling but you have a problem that is causing your car to run lean have you changed the ecu over with another to eliminate it from the list if you have and its still running lean then the fault lies elsewhere.

Daz, I'm sure I suggested you put the car on a rolling road which can also do diagnostics. Have you done this, Peter Burgess at Alfreton would be my recommendation?

ETA, or Trackcar if you fancy a slightly longer drive

The chip will be a conservative improvement over the standard map that Mark has determined through his experience to be suitable for all cars with that particular engine configuration. A custom map will be tailored to your car through a live mapping session, so it will still be safe for your car but closer to the limits giving you potentially more power and torque than the generic map. As always with mapping the first thing is to get the car running as well as possible in standard form, so if you have any underlying problems get them sorted with the car in standard form first before you move on to generic or custom maps. Re fitting the generic chip and then getting a custom map as has been said I'd call Mark and ask him how to proceed.

My reason was i changed the engine from a 4.0 to 5.0 with cam, inlet manifold, inlet trumpets, other induction mods, and reused 4.0 ECU and complete injection system. I wanted the engine to be smooth as silk and very driveable. The 4.0 shunted a little around the 1200-2000rpm. Result was fantastic. Great drivability and economy compared with the 4.0.

Why dont you get back on that free Rolling road, and simply adjust the fuel pressure for maximum power flat out, and then let the ECU sort out the less than full power fueling ? As long as the car does not start to snatch at low RPM, then everything is just fine. Job done.

As for the Generic Tornado and the like, these are improvents over Range Rover mapping, but much less so with TVR mapping, so the gains would be much smaller if at all. Dont over complex things.

im going to peter burgess on wednesday, i have a tuned mgb , he supplied the head and cam , so i will have a word with peter .RPI TOLD ME THE DIFFERENCE WILL BE VERY NOTICABLE AND I WILL GET 4 TO 5 MPG MORE , MORE POWER AND SMOOTHER !(off the shelf chip )

Yes, that's typical






of the things that RPI will say to get a sale

Ouch!

Take it with a pinch of salt

Thats pushing sales talk a bit too far. I dont know how you would manage that as you cant alter the actual lambda fueling region (you can only tweek the amount correction the ECU applies to the map), and if you save fuel in the open loop area, chances are the engine going to be horribly lean, and thats not what the Tornado chip is about. The biggest fuel saving takes place at start up where both the Range Rover and TVR map over fuel horribly for about 30 seconds until the lambda probes start to work, but not 4-5 mpgs worth unless you start the engine cold, then run it a 100 yards each journey. Why dont you ask them for a full money back guarantee if it does not do what they say --if you really want one that badly.......
