On the contrary, you're missing a problem that most definitely will be there - the B230FT was NOT available in the 740 and requires 48 pulses per turn of the wheel to assess speed correctly.
If it is a non-ABS car, it will give 12 pulses per turn of the wheel, if it has ABS it will give 96 pulses per turn before the converter and 12 after on the back of the instruments.
This will give a false reading to the speed input circuits of the LH2.4 Jetronic ECU.

However, you're right about one thing - the problem won't be there as the OP has decided to go for a bit of mild tuning on the B230E instead so no EFi will be going near this car and therefore no problems.
