Mark Adams Tornado Chip

[bogbeast]

I am considering buying my Griff 500 an early Xmas present (on the basis its gets more use in the summer..!)

I am considering a Mark Adam Tornado chip.

I know that he does an 'off the shelf' chip that contains his best guess for he engine. I understand that comes in at approx £350 and makes a significant difference as regards general drivability (less shunting, generally smoother etc).

For the full effect I would need a rolling road session to bring out the power, at approx £750

I am planning on upgrading plenums and exhausts early next year and don’t want to fork out twice for the r/road session.

If I buy the off the shelf chip now, can this be reprogrammed during the R/R session (hence saving a bit of money) or will it be the full R/R price?

The existing chip can be reprogrammed. Either that or Mark will give you a new chip included in the rolling road time (I believe the chip is quite cheap, you are paying for the program that it encoded into it).

Rolling road time is expensive if there is anything else wrong with the car. I would get it serviced first.

I rencently bought an RPI 5.3 engine with an ACT triple Plenum. Included was a Mark Adam Chip.

The engine was running quite bad. At the end I had to let everything reprogrammed from scratch with the help of 2 rolling session. It was not an isolated case because another customer was in the same situation (He has a normal TVR 5L engine and a new plenum). Now my engine is running much better, I even broke my gearbox.

My advice : Save 350 pounds and do the right thing from the beginning

IF your ECU has a ROM you will need to swap it for an EEPROM (HW costs : 1-2 pounds if it's a classical 8bit 64K EEPROM).

Ask the technician to use the actual TVR ROM as basic mapping for the rolling session. After determinining your ideal mapping he will burn your EEPROM and plug it in your ECU.
