ECU Remap

[Nimbus117]

Has anyone had a remap? plenty of companies claiming an improvement of 20hp and 30nm torque for a 2.7L but not seen any posts anywhere from Boxster owners who have done this.

I also have a Civic Type R, Hondata Flashpro is a very popular DIY loadable remap for these - if you can justify £550.

As your topic appears to be a DIY question (rather than a DIY Tutorial), we have moved it to the appropriate forum.

Thanks Loren.

I assume by the lack of response that remaps are not popular. The Boxster offers good gains 30-40hp for not much cash by de-snorkelling, replacing the induction pipe and a remap. Would be good to get an owners opinion of a remap rather than the claims of those selling them.

Would appreciate any comments.

Cheers

Well, it has been written here before as well as in my blog.

You will NOT get any 20 - 30 HP from a "chip/tune" on a normally aspirated engine. You might get that much if put a larger throttle body on the car, headers, free-flowing cats, and the tuning chip... maybe. But that would be lots of money with no guarantees. You could easy engine with a large flat spot in the torque/power curve - I have seen that happen too.

If you really want a lot more power trade the car in and buy a turbo. And if that still is not enough throw a chip, GT2 exhaust, and heavy duty diverter vales on the car - and you can likely come close to 700 HP. Then save your money for tires... ;)

Thanks Loren,

I tried searching on here and didn't find anyone who had a remap. I was sceptical but then some manufacturers do turn down the power on lower models, to justify the price of the expensive ones or make you buy the latest model.

I am happy with the power, if a simple remap would result in 20hp as these companies claim - sure I would be tempted.

Just to put my 2 cents in... Agree with Loren that the HP claims for an ECU flash on a normally aspirated car are "aspirational".

But.... I had a 99 Carrera that had Fabspeed mufflers and their chip. I don't know how much HP I gained but it made the car more fun to drive. More responsive and quicker from 0 to 80 mph...

I would try to find a shop near you that tunes Porsches and see if you can drive a car like yours that has had an ECU flash. Then you can decide if it's worth the money.

Thanks Phil,

Dont think I will bother with a re-map. If there were owners raving about the improvement, I would give it a go. A total lack of this anywhere on here or elsewhere on the internet for the Boxster makes me not want to try. I have de-snorkelled the car and liked the increased induction roar. This week I bought a second hand EurocupGT highflow induction kit on Ebay for not a lot so that will do for engine mods. I have always been intrigued at the way Porsche and other manufacturers space out the performance on their different models (often with the same engine) to make the top models more appealing. Reducing power via the ECU is a cost effective way of doing this.

As I stated at the beginning, I also have a Civic Type R. A remap with the Hondata unit makes them much more driveable, it's amazing that Honda made such a poor job (the european model). The Vtec point is set way too high (5500rpm), it's much easier to live with if this is reduced to 3800rpm (at full throttle), the mid range improvement is much better and reducing the need to drop two or three gears to make it move . Also the limiter is raised to 8600rpm, we did some work on this engine for Honda a couple of years ago at work so know all this is safe and the right way to go.

Thanks again for the advice.

You might notice snappier throttle response (read touchy throttle) since typically a remap will advance ignition timing, but it certainly won't translate to extra HP. If you have warm air intake a remap can trick the MAF into thinking it is getting colder air, again not going to translate to more HP. In other words, in most cases, it's not worth the money unless you've poured multile thousands on other upgrades to compliment.
