Ibiza 1.4 Sport engine lag

I've just come back from the re-mapping place and the re-map of the ecu has done next to nothing. It does pull slightly better in the engines powerband but other than that, that lag is still there. I've been doing more research and apparently the lag is actually there on purpose!! It's meant to give the majority of drivers (people who drive mainly for comfort than for speed) a more smooth ride. My last hope is to get a Sprint Booster and see if that helps cause i'm fresh out of options after this one!!

Right, I've had the sprint booster for a while and it doesn't help with the lag at all. It does make the car's revs increase faster but the lag is still the same. I'm getting rid of the car in a few months so I'm not spending any more money on it. From what I've read, the lag is in built to the throttle pedal as I said in my previous post. I guess what this means is that to sort the problem, get an after market throttle pedal. I hope this helps anyone out so they don't waste the same money that I did trying to fix a problem because the manufacturer thought it was a good thing.

Its the motor/actuator in the throttle body, its just simply slow and horrible. No device could accelerate the movement in the TB, even this so called 'Sprint Booster'.

Your best bet is to convert to the older r4 16v throttle body that uses cable systems, but this would mean using a standalone ECU.

I believe the older 1.8t throttle body (mainly on mk4 golfs) fits on the intake manifold and uses cable at the same time.

Ahh, now that makes more sense it being the motor in the TB. But like I said, I do actually have a Sprint Booster in my car so whatever it's doing, it does make the car rev a lot quicker and when I changed the throttle body, nothing changed either. I was tempted to convert back to the old drive by cable system but since I'm replacing the car, not much point.

What throttle body did you change too? If it was another 85ps TB, then they all have the same slow motors.

The sprint booster looks like a pedal accelerator that simply tells the ECU the pedal is pushed further than you are pressing it. In other words, an expensive resister ;)

I changed it to pretty much the same throttle body to be fair, it was a throttle body from the '08 1.2 Ibiza. Just went on the same model number etc. From what I saw, there weren't any issues with that model of car unless no one noticed it. But yeah, I guess that's exactly what the sprint booster is. So I think that means that we are agreed that it is definitely the motor in the throttle body which is causing the lag and not the throttle pedal then!?

Possibly the most stupid system for "comfort driving" ever put into a car. It makes it worse!!
