Many H4 customers have been complaining over the years on the Lag/delay and the performance of the 4EAT to the point of selling their cars or just no attempt to drive in a way that would cause an accident like over-taking quickly, etc. In other words, downright disappointing and disgusting, leading you to denial and constant frustration
Some tuners are able to offer tuning, like XRT (Xtreme Racing Tuning) where the 4EAT performs better. Some does it better and I believe XRT through feedback from its customers, shows just that. We do it better with continuing success and we are happy!!!
Generally, the following are expected when the ROM is tuned (The Transmission Computer is not tuned):
- Quicker shifting
Firmer shifting
Appropriate gear selection for less labouring or load on the engine
Less ping/knocking due to the transmission wanting to be in 3th to 4th gear all the time.
Less pedal moving to make the transmission shifting
Better fuel mileage
Easy over-taking and maneuvering due to quicker acceleration due to the above points.
XRT Offers additional stages in 4EAT indirect tuning.
- Stage 1 allows the transmission to shift and operate more efficiently than the Stage 0 that comes in the General tuning.
Stage 2 offers greater shifting and operations. This is the mode many requires if you want to have full control when the transmission shift for hill climbing, racing, over-taking etc.
