Does anyone know any places left that can do this? Been wanting to 'finish' the conversion for a while. Managed to get my sticky paws on one of those 3.5bar porsche fuel regulators, which I don't want to fit quite yet, (not currently driving the car) but ideally a remap would be the way forward. I emailed TSR as they are sort-of the closest well-known VAG specialist to me that I know at least used to do this kind of thing, but to no response so far. I'm in Cornwall, and don't really want to travel too far to have this done. I think there are a few Superchips dealers around me, which I guess could do it, but someone with a bit of VAG knowledge would be preferable. cheers!
I remember reading a post about someone on ebay who seemed to be doing it properly (not Blitzchips). The reason I say properly, is because they seemed to be replacing two chips in the ECU. Have a dig and you might find the thread. Other than that, it's megasquirt time
the 2 chip thing was only about certain ecus being different, the early ones need 2 chips to work properly, the later ones need 1. Or the other way round, but iirc it was the early ecus that needed 2 chips.
My logic was that if the seller was bothering to find out what you had, there's a chance that he actually knows what he's doing!
Ah ok I thought you meant there was a guy doing proper remaps rather than selling the right chip(s) for the ecu application I got all this double chip info from the vortex member 'vw_pilot' really knows his stuff and is well regarded in general over there too. Sent me a couple of chips for my ecu cheapy too. If you get a pack of 2 chips this is suitable for both types of ECU, you just dont use the 2nd chip if you have the later ECU From what he was saying basically all the 2nd chip does is convert the ECU to the later type, the map is still on the 1st chip. Something about on the older ECUs part of the map is on the older chip, so it goes a bit funny if you use the wrong type o chip. edit: and you can tell if its early/late from zee party number, single letter on the end = early, 2 letters = late
So can a new chip be burnt for me on a rolling road or is this not possible? I thought I could have the fuelling map burnt especially for my car. If not, I actually bought a couple of chips from that vw_pilot guy about a year ago and they never worked. I tried them several times, and nothing. I think I also tried just the one chip to see if he had made a mistake with my ECU number, but still nothing. The fuel pump wouldn't even prime. He offered to send me a new one, but I kinda lost interest in the whole chipping thing after that to be honest. You ordered some off him as well didn't you John? IIRC yours worked fine! (can't be assed to find the post) I'd rather that than megasquirt, that's a bit out of my financial reach...
Well I emailed vw_pilot to see if he'll still let me swap my non-working chip for one that works a year later.... we'll see. Do you know if his email is still vw_pilot@hotmail.com? TSR can't so the remap, unfortunately, and basically said no-one can. I thought back in the good old days, when a car was 'chipped', it was done properly and remapped for each car on rollers? Was it just a case of bunging some pre-mapped chip in the ECU all along?
the digi 2 ecu can have the fuellign re-mapped, mine was actually over fuelling significantly. jabbasport did mine, called it an emulator. im sure they put there own ecu on which is wired up to a laptop, a lambda sensor or similar up the exhaust pipe, they basically do afew runs on the dyno and modify the fuelling map to fit, then sort that on the chip, open your ecu up, replace chips and your go. cost well over 100 notes though cant remember if they did much else, but when your exhausts spitting flames it has to be done corwall is along way out cant be many places round the country that do this to mk2's nowadays.
Well over 100 notes isn't too bad..... I was expecting it to be 250 at least. Like I said, TSR can't do it, could try Jabba sport or Stealth. Maybe they've done a 2.0 conversion before and kept the map.... that would be nice.
yeah I got a pair of them from vw_pilot and they worked great, both in an old single letter ecu as a pair and just the 1 in a newer 2 letter ecu not sure if his email addy has changed since its been years since I emailed him last, may be worth dropping a pm on thew vortex if you're a member.
If you can get someone to recalibrate the fuel tables using an emulator and a dyno, I would suggest this method rather than some dude sitting at a desk in the US and flashing fuel tables for 91RON fuel. This is the best compromise apart from switching to a full standalone where more importantly you can also optimise spark timing.
my mk2 digi had a 2 chip remap (actual remap) from amd back in the 90s. from what i read, one chip may have done ignition and one did fuelling. is that likely to be true?
Depends on what you read and if there is any fact in that statement. I do know the fuel tables are on the ECU Eprom/s. Still Yet to see factual evidence that the spark tables reside in off CPU cache.
Jabba want 350 all-in for the remap. Seems steep. I'll wait to hear from stealth. Would they burn me a whole new Eprom or just recalibrate the fuel map on mine? Also- you have a point on the 91-RON fuel issue. I never thought of that. Especially seeing as I try and run on the fancy high octane stuff. But for 350..... ..how much would we be looking at for a Megasquirt ECU and get the timing done as well?
A Megasquirt ECU and harness could be had for about the same, from a reputable source. You could pick one up for less, if you're good at electronics, and can build it yourself. Ideally you want a throttle body with a TPS on it, but you could manage with the standard digifant hardware on it. You'll also need a laptop to do the tuning, so if you don't have one, that's additional cost you'll need to factor in.
Got a laptop- so thats good. if i could get megasquirt for 350 then surely thats the better option? Thats before i factor in getting someone to a) wire it for me and b) set it up for me. Which i'm guessing are not DIY have-a-crack jobs.
You need to get hold of Bilal at SNS tuning mate. Bilal@snstuning.co.uk That or Darren at G-werks should be able to sort you out
Exactly! I'll wait to hear back from them. Did it warrant the cost with your car? Weird to see that it was overfuelling- it seems to be common assumption on here that digi's run lean. 152-not bad at all. Megasquirt has got me thinking though! The car is not going to be my daily driver anymore, so even though I know megasquirt would probably be a bit out of my technical ability, it seems to be a learn-as-you-go kind of thing anyway. I'm gonna go back and read Toyo's megasquirt thread later. What components on the digi would I keep and what would I need to change? If we're getting into different injectors, different dizzys, different TB's etc etc it might be better to stop thinking about it now!
