Hey all,
I've just installed TCIP4 in my 1997 TRX, it's almost completely stock apart from a Bafflectomy. It has 52,000 miles on the clock, I recently finished a top end rebuild (valve oil seals, piston rings, reseating valves ect) so thought the TCIP4 could be justified once it ran smoothly, the low rpm first gear throttle jerk was doing my head in.
I programmed the TCIP4 with the TDM850 preset option, I did have to change a few things initially;
- Tachometer out put from 2 pulses per revolution to 1 to get a accurate reading
- Used the Tachometer test function to calibrate the read out (-4% correction)
- Revolutions without ignition from 1 to 0
- Calibrated the TPS sensor 0% and %100 ranges (but left in the sensor no option)
- Set the limiter from 11,000rpm to 10,000rpm
- See here for screen shots of all the TCIP4 program tabs with the settings I'm currently running:

Now here is the problem (apologies in advance if its glaringly obvious).
The TCIP4 dose eliminate the low end throttle issue and generally feels more refined on the standard TDM 850 map. Unfortunately this is only once the bike is up to temperature (reading 60-70c) if its taken above idle before hand (+1400rpm) and or under any load it produces a stutter clunk and momentary loss of power. Obviously this is alarming and unpleasant, I've swapped back to the stock ECU and the problem dose not persist. I'm thinking that what I'm hearing is knocking/preignition but I don't have the expertise to properly diagnose let alone start tampering with the advance.
Has anyone had a similar experience?
Have I missed a basic setting in the TCIP4 software?
Could I solve this by adjusting the advance at low rpm?
Any and all advice welcome, many thanks. D
