Electronic prob

[BadTy]

Hi guys

Take an electronic prob on a customers Ty. On WOT it takes fluctuation of RPM. If i accelere slowly (not WOT) it runs normally. Stock chip. replaced already: o2 sensor, spark cables + CR42TS spark plugs, cap and rotor, no DTC`s.
Some months ago i replaced the engine. All sensors and filters new.
Someone can help me?
How I can upload a datamster file?

Wastegate overboost. Check for free movement of WG rod/arm.

Also make sure it's not activating the rev limiter on the stock chip. ~4700 RPM.

What brand of spark cables did you use?

Re: Electronic prob

I use the OE plus performance cables from Standard 7mm,
Datamaster shows the boost target on 16 psi. Max boost acc. to DM is 15.5 psi. But the aux boost gadget displays on WOT shortly over 20 PSI.
If it possible i like to send you the DM- file by email.
Please let me know

Re: Electronic prob

Did you gap the CR42TS at .035" or tighter (as tight as .025")? Too big a gap will blow the spark out and cause tach flutter and engine stutter.
