TURBO /VITESSE UPGRADE SETUP ECU AFR

Hi I have done the Lindsay racing upgrade ,mine is finished and ready to run but I am concerned about setting the car up ,at the minute it has the LR piggy back board on the ecu but I am concerned about the fuelling .If you have done this upgrade Are you running the standard ecu?if not which one did you choose? and have you got a AFR controller ? if so which one?My car has the rogue tuning VITESSE MAF kit as well .I am considering the Augment ECU upgrade with a AEM AFR controller gauge .Has anyone done this ?
Finally has anyone changed the headlights to LED units ,if so how did it work out?

 
Does the piggyback have any kind of closed loop system or is it one whereby you can make tweaks but need a separate Wideband AFR sensor and gauge to monitor?

I had an Innovate wideband in the past but the AEM system is pretty dependable too. If you don’t have any type of EBC with your current setup then AEM do the Truboost (IIRC) that is an EBC and AFR in one gauge.

I‘be looked at the Augment systems but couldn’t reconcile the significant costs as everything I wanted seemed to be an optional extra.

I’ve also fitted LED bulbs into the regular housings. It’s a bone of contention with some as the housings are made for the cutoff of a halogen bulb not an LED one but with a bit of playing (tape on the garage door beforehand and line the new bulb beam up) I’ve had no MOT issues or suchlike and am actually able to drive at night!

 
Hi thanks for that, I'm unsure about the route to take next . The augment ECU has the ability to be monitored and adjusted via a laptop .The existing ECU I'm told will have to be set up by Wayne Schofield as he's the only guy who knows how it works well enough to fiddle ,but visiting him I'm told will be about £600 and he's up north so a long day with the trailer in tow .further visits are a repeat procedure and cost.The car at the minute is massively over fuelling due to the larger injectors from the Vitesse kit .the augment ECU will need a AFR gauge but the imput is analogue so I'm unsure if the AEM is compatible in its digital or analogue format.

What I was hoping for is to find someone who has done this upgrade and how the problems were overcome.

Regards

John

PSH is running a Vitesse system so he’s your best bet for help with that specific MAF setup.

From hazy memory I think there are different maps on the Vitesse board and you’d need to select the map that corresponds to the injectors you’re using.

Wayne Schofield is good but as you say, there are issues around getting there and costs involved too.

A piggyback solution is only ever going to be a halfway house to modernising the ECU. I had a chipset, electronic boost controller, adjustable FPR, AFR meter, etc. and got frustrated that nothing talked to one another and there was always a compromise somewhere.

I’ve since ditched the lot (actually, I tell a lie, I still have the Apexi AVC-R EBC boxed up in a cupboard) and gone to a VEMS stand-alone system. It’s not been without it’s teething problems and has been a reasonably steep learning curve at times but I’m very happy with the adjustability and control it gives me For my specific purposes. Yours may vary, there’s no “one best answer” here - but deciding what you want/need in advance could save a lot of time and money.

I'm afraid I'm a bit confused? LR piggyback, Rogue Tuning and Vitesse? All on one car?

I can't speak for Rogue Tuning other than I don't think they are as good as Vitesse. Did you get the Vitesse direct from John?.. if so it should be reasonably well chipped as John would map it to suit the car and should start up and run very well. Vitesse have their own piggyback system which will allow you to adjust fuelling with your laptop if you have the MAF V+ version this will include a 3D MAP sensor to adjust timing. This will also include a set of jumper switches for 8 different maps on the ECU. The standard ECU combined with Vitesse is capable of delivering much more than many realise, it will also be ultra reliable.

In answer to Martyn, the Vitesse is closed loop. I think we need to know more on the car, it's mods and history to help...

I’m going to make a couple of assumptions here (and we all know how well they can go) - I think the “Vitesse” part is a red herring and it’s the Rogue M-Tune from Lindsey Racing that we’re talking about:

https://www.lindseyracing.com/LR/Parts/ROGUE-944MTUNE.html

In which case it comes with switchable maps for the injectors etc. that were specified when it was purchased. (Unless it was purchased used, in which case - you might not Know what’s on there).

Looking at the 4 different Tune setups then it seems most likely that you have “Tune 1“ here: https://www.lindseyracing.com/LR/Parts/M-TUNE.html and that shows you how to adjust the maps via the dip switches.

If it’s a Vitesse system after all then John at Vitesse is your best bet for help: http://www.vitesseracing.com/html/performance_kits.html

 
Does Lindsey M-Tune idle properly out of the box, and do Lindsey know how to resolve any software issues? IMO one of the best things about M-Tune appearing is it forced John Joseph pull his neck in regarding pricing and support.

 
If it is Vitesse John is unlikely to be able to help, he doesn't keep details of customer car maps, something he made clear when supplying mine that I need to be sure to keep back up's of the jumper switch position details.

To the OP, did you install the upgrades or did they come with the car, are they new from the manufacturer? You say that the car is 'massively over-fueling' if the car is new to you and came modified the first thing that I would do is check the FQ switch to ensure it's on '0'. This switch controls fuelling and timing on the original ECU, used really for countries with poor fuel quality but was also used by modifiers to adjust fuel/timing.

Yes that is a confused set up, Vitesse MAF as far as I know needed the Vitesse chipboard in the ECU. Any Wideband sensor and associated gauge will tell you what the mixture is like (Will need a bung welding in the exhaust - usually done just as the exhaust pipe is about to head under the cabin floor on a 944) you will then be able to play with the ecu switches links according to the chips / board in the ECU to see how close you can get with what you have.

You can also get a piggyback e.g. http://www.vitesseracing.com/html/piggyback.html to massage the fuel and ignition - I think it is actually a https://www.perfectpower.com/index.php/products/piggy-back unit form here and they are bit more from vitesse but you get the wiring diagrams and base settings for a 944 if you go the vitesse route. This needs some skill to set up and is just an extra box outside your existing ecu. Your ECU may have many years of happy operation left but it is already 30 years old so it may not!

An Augment or VEMS is a custom new ecu for the 944 as that should have more years in it than the original but they were designed on smaller budgets than the bosch original.

The ultimate solution maybe to go with a Motec / Link or similar standalone system - that requires a lot more work and ideally you want someone who is an expert on the chosen system and on the 944 - you will also need to spend some time on the Dyno to optimise the setup. ( I think that there are some tricks to getting the best out of a 944 engine - thats how off the shelf chips were able to produce more power than custom chips by Wayne back in the day - I don't doubt Wayne now know those tricks as it would have been in his interest to decode them!

The cheapest option will be to throw in a wideband ands see where you are on the current set up with its dip switch options - then if needed go and see Wayne.

I believe all the chip / boost options come with an upgraded (3bar) fuel pressure regulator - you didn't mention that - and most have the option of bigger injectors.

You also want to make sure (pre Wayne) you haven't got any boost leaks (pay particular attention to Idle stabiliser valve / throttle body / small vacuum lines / intercooler couplings and you will probably want to do something with the wastegate and boost control system.

Whereabouts are you located?

Best Regards,

Tony
