Hi i'm having a couple issues after fitting a new remap chip to an msb ecu in a 10p td5, to begin with i had a remap chip which was fitted by the guy who had the car before but it struggled to get past 3,000rpm and felt underpowered.

So i bought a new chip from boottune with a rev limiter that is supposed to come in at 4,000rpm but when the engine is cold or on the first start of the day it seems as if the limiter is kicking in at about 2,000rpm and throws a load of greyish black smoke out the exhaust pipe. i have a nanocom and have checked everything but i can't find anything out of the ordinary.

OK, can you confirm that the actual injector codes are saved in the ECU memory as they phisically are in the engine? beside that record an "inputs fuelling" log with nanocom and post the file here then i'll tell you more

Read the saved codes with nanocom in td5 engine settings and compare with the codes on each injector they are from 1 to 5 starting from the front of the engine, wrong codes can affect the power above 3000rpm, it's explained here, quite the same procedure with nanocom too

Thankyou i will try this, but car has original ecu, would the tuning chip be able to change the injector settings?

The remap doesnt change the injector codes but are you sure that the injectors are also originals from factory in the same order?

I just checked the injectors and all the numbers match up but the last letter of every number is A but on the nanocom it says M
