Tony_205 1 Posted November 20, 2006 I have been offered a chip and remap for 150quid. This is a trustable source who does it for a living so theres no worries there, im just trying to find out if it actually makes a difference on a 1.9 GTi. My engine will be standard apart from a performance air filter. I want to keep my new GTi looking totally standard so this seems to be the first step to modding it - and with this, what sort of power increase should i be expecting? 3-8bhp? What do you lot think? Is there any drawbacks etc which i should know about? Share this post Link to post Share on other sites

Super Josh 4 Posted November 20, 2006 The Jetronic system on your doesn't actually contain a digital 'Map'. It is an analogue system that uses the output from the air flow meter and the coolant temperature sensor and throttle switch to control the injector duration. The spark and advance curve are controlled by the distributor. So the chip and remap doesn't exist. You can buy a small piggy back board that will alter the fuelling a little and can remove some of the kangarooing, but you would be better off getting the car on the rollers and making sure everything is set up as it was from the factory Should cost around 50 quid and well worth it.

taffycrook 2 Posted November 20, 2006 This is a good question and worth answering with an example of how good the std ECU is at coping with increased air flow and thus power. If the std 1.9 ecu is used with a mi16 engine it can still cope with the fuelling of up to 165bhp in one example I have tested. Now a good 1.9 with an exhaust and filter may just about make 130bhp.

Tony_205 1 Posted November 21, 2006 As mentioned above, i will be keeping the standard exhaust system, iv heard this is not worth being changed? Was going to get a group A full system but if there is a chance ill be losing power and torque then whats the point? Whats the next step to getting more power then guys? Car is standard apart from filter. I dont really want to be messing around with Cams etc either at this stage! Share this post Link to post Share on other sites
willxs 0 Posted November 21, 2006 i dont think there are many 'small' mods you can do to achieve power. a set of carbs would be a good place to start (or bodies if you can stretch to it). just strip it out. cheapest mod and you gain power-to-weight which is Just as good.

number2301 1 1 Cars Posted November 26, 2006 If you're after a remap kind of thing there's always the Motronic conversion, just search for Motronic or MP3.1 and you should find something. Share this post Link to post Share on other sites
