Re-Mapping

5th September 2007, 12:23

i have a 99 vts. when i bought it, it was standard apart from an fse fuel jobby. after reading your forum i gather this must have been a waste of time as it was standard so i've added a pipercross viper, 4-2-1, de cat and magnex cat back.

was going to buy a superchip to optimise all the mods but i've also read on here you can remap the origional ecu, is this defo true as i'd rather have that done if it will work?

anyone suggest a place to have this done? i live in lincolnshire?

one last thing, i got given a gauge for testing fse fuel pressure with the car, what should it read when i screw it in when standard? and with the mods?
can this be set properly when a remapping is done?

thanks in advance for advise!!

Glad you've done a little research before raising this question. Here's some advice...

Get rid of the boost valve for starters, it's not required. Secondly, you don't need a re-map with your current setup, it would be throwing your money away. Finally, avoid "chipping", or something like Superchips for example. A re-map is fine, but 1) You only want to do it when it's required and 2) It's not the most cost effective way of setting up your engine management anyway, plus, there are many downsides to capabilities of mapping a stock ECU when compared to setting up a standalone mangement system.

Mapping is 9 times out of 10 the last task.... so you want to get the parts you want on the engine before. You have the most common mods on which are crying out for cams

Mapping with breathing mods is fine if you aren't going to take your engine modifications any further..

People will say dont bother but it will make a difference..

My friend had a furio, i have a westcoast..Both had the same mods like exhaust etc but mine was stripped out..I used to beat him when we had a play, he got a remap done and when we hit 3rd and 4th etc he flew past and i mean flew past..His map made a huge difference..

As Toad says, dont bother with a chip, they are crap..

Angel Tuning will come to your house and map your car so will a company called V-Tune..

Search them up on google for their websites..You wont go wrong with either of them..

i dont really want the hassle of fitting cams!! sounds good but moneys tight at mo. possibly in future? also cant take off fse thing cos i didnt get the origional parts that were replaced. anyone know what pressure i should set it to with this gauge thing though?

i just want to make sure everything is running as it should. efficient! i thought by making it breathe in and out better it would be good to make sure there was enough fuel going in? re-map?

you wont need a map just for a filter and full exhaust bud.

You wont NEED one..

BUT

You will benefit if you had one..

Figures which are quoted on the remap sites are on std engine with no mods and saxo's get about 8 hp and some more torque..You will notice it, trust me..

telling me you'd pay 500 + pounds for a map of a standard ECU for an exhaust and filter?

5th September 2007, 13:09

Group N chip is giving good performance. Give 2 degrees advance on the intake camshaft and 2 degrees retard on the exhaust and you will see good increase of performance.

£200-£250..

It's not that simple James. You gain performance from "re-mapping" depending on what the current state is. I.e., if your car is not fuelling perfectly, a good re-map will take care of this. It would be foolish to assume that you can just re-map to gain power, as I said, it's not that straight forward. Take your N/A car to Superships for example, you could pay for the works, yet not gain any performance if your car was already running spot on.

The ECU and lambda setup in the 106s and VTS (for example) are capable of changing the fuelling, ignition timing, and WILL do this and will always try to do it for best performance. However, they will still be limited to a safety margin with the fuelling, I.e., they won't allow it to run too close to being lean, as of the risk of overheating, and causing damage to the engine.

The reason you require the re-map after fitting cam shafts such as 708s, is because the stock settings can not adjust the fuelling to the required amount for an optimum fuelling. There's also lot's of other things that are / should be done during a re-map with 708s, such as cold / warm starting, ignition timing, etc, etc.

As I've already stated, it's not worth the money in the current situation that the car (listed above) is in.

isnt that angel tuning that dodgy chip you showed me before Toad where I email them what I want? lol

5th September 2007, 13:19

Ok Toad..

I'm not arguing over it..but these remap companies gaurentee increased power etc or your money back and stuff..

I've seen many cars have remaps in all states of tune and the difference has been very noticable.

They aren't dodgy, they remap your car with a laptop at your house etc..They dont put a chip on your car..

5th September 2007, 13:23

hmmm? not really sure on all this. i'm gonna have to do a bit more research before i start spending! its a peace of mind thing rather than more performance. the car quite quick anyway!

can anybody help me with this fse thing? what does my fuel pressure need to be? in bar or psi? just want to check its ok!!

5th September 2007, 13:24

There's potential for a stock car which has just come off the showroom floor to gain performance from a re-map. I'm not arguing with you James, read what I've said dood.

It's the fact of whether it's worth doing it...

Soul, I haven't looked at the link. That thing was called Response. Still don't know how they can get it to work... Novel idea, I'll give 'em that!

5th September 2007, 13:26

Misterwit, get rid of it, that's the best thing you can do.

5th September 2007, 13:29

i would but it means sourcing some o e parts to put back? i dont have them and dont know what they are?! pipes etc have been cut. just want to check this ones ok, correct pressure and leave everything be!! like i say it seems to run ok?

oh sorry my bad, got the two companies mistaken.

5th September 2007, 13:34

OK... Bit of a pooy situation. They only way you will know it's fuelling perfectly, is to get it on a rolling road. You've taken the CAT out right? They will just prod a lamda up its arse and and take the readings throughout the rev range for you.

It's worth doing, you'll probably pay around £50 for an hour session, which should be all you need. Then you also get a lovely graph you can take home and frame.

Response charge £499 too!

13th September 2007, 13:53

Angel tuning do do a group offer for multiple orders of remaps. Think it goes down to £180 ish with 20 people iirc....

Don't quote me on that...
