Cupra mini build thread - Blanco Gringo!

Will you bring this to Nationals?

Will you bring this to Nationals?

Will try to.

Wheel alignment done.

Last items are arrival of the EPROM and a proper exterior detail.

Then time to get a new project... :-/

[mikinoz]

Completed tonight. EPROM in and power delivery is so much better.

[Water Boy]

Very nice.

Would love to see a before and after dyno plot etc!

Might get an after one done, but I can't be bothered getting the ECU out again to plot it stock.

Stock ECU socketed or do you have to desolder the original chip? Is the upgrade worth it on a stock ABF?

[Bora Sport]

They just push in. No soldering necessary.

[crazyazz]

What did it cost? Im tempted if it makes a perceivable difference on my stock GTi

Push in.

Is the upgrade worth it on a stock ABF?

Yes. But there are so many other things these old engines need to have working properly before you get the full advantage. O2 sensor was the biggest gain in performance before the EPROM.

[crazyazz]

It seems to be running fine, anyway I can use VCDS to determine if my O2 sensor needs replacing?

I can't remember the exact price but around 250 euro.

As for the O2 sensor, I just replaced it as a matter of course, got one from UK for $70.

Shame you are not closer otherwise you could test it. I would get an adjustable cam pulley too FWIW.

[crazyazz]

You have an adjustable cam pulley installed to adjust cam timing to correspond with EEPROM map?

The cam pulley is there regardless. It helps without the EPROM too. Advancing the cam timing brings the power band down in the rev range to make it more usable. The car now has pretty linear feel to power delivery - I suppose I need to get it on a dynamometer.

[crazyazz]

That would be cool. I found this dyno chart on a stock ABF with garlock, looks like gains of 14KW at the fly

[mikinoz]

Think I've done an injector on #3. Leads, plug, new cap, button and still no love. Fingers crossed that's all it is... Will pull it out today to check and test.
