Hi guys

For full complete comparison I would have look on 22b forum

And please read Pat reply to this thread

Thanks,Jura

 

Fair point and obviously like you say, people can charge whatever they like.

So does £450+vat also apply to mapping an Alcatek or is the syvecs more difficult hence more time and costs involved ??
Also, is LC and AL £150 for both or is that each to add them onto the Alcatek .?

 

Syvecs is a little more expensive with Alcatek mapping costing from £350+ vat depending on how many fuel/ign/boost maps you're doing.
Syvecs isn't more complicated, just more time consuming as you have so much more to configure for during and after mapping.
Setting up the datalogging config for instance so it's logging only the stuff relevant to that particular car.
The motorsport package is now just £100+ vat which adds ALS, launch control and the flat shift option. This can be utilised using a momentary lift or a clutch switch, Tim from JTinnovations sells them with a handy harness which plugs right into the green diagnostic connections above the pedal.

 

It really doesn't matter how many maps the ecu has available. All you need to do is plug in your laptop and flash any saved map in there. Simple 👍
My MS2 has duel maps switchable externally, however if I need more maps I simply save them to my laptop and flash them accross in seconds.

 

The problem with that is you want to be able to swap maps on the fly most of the time, especially when it comes to various boost levels.

 

I see, not wanted to do that personally.

 

I currently have 7 calibrations on mine, 5 of which I'll switch between at the strip and 2 more for pump fuel/road use.
The strip cals have varying degrees of total boost, boost off the line, 2 NOS maps and the launch rpm which is variable through the Toucan touch screen.

 

Depending on the grip levels?

 

Exactly, our local RWYB strip isn't famed for massive grip or consistent weather conditions so I alter the car accordingly. Having it all preset in the ecu saves buggering about too much.

 

To compare 2 ECU's one of which is nearly double the cost of the other isn't really fair.
If you want all singing all dancing buy syvecs
If you want a good aftermarket ECU that will do pretty much anything your run
of the mill person requires buy Alkatec

I personally bought Syvecs. Second hand value made it more affordable
At the time there was issues with injector drivers on Simtek which put me off.

 

Just out of curiosity - could you, please, elaborate?

 

Basically the part of the ECU that drives the coil in the injectors used to fail.
I know of at least 1 engine failure due to this.
I believe the issue was sorted free of charge and the updated ECU no longer has this issue

 

Only half the story as always with these things. Alcatek had one batch of v3/4 ecus that had the possibility of an issue with an injector driver. Any ecus from that batch that were sent back for reprogramming for another mapper, or updating or for any other reason had all of their injector drivers replaced free of charge.
The issue is old history and it's not like other manufacturers don't have issues of their own.

 

Use a mapper that knows what they're doing then! A number of mappers do not know how to get the best out of the OEM ecu's.

The standard ECU is extremely powerful, depending upon variant and year.

 

you know who maps my car so you know full well he does

 

Who maps it - Pat?

You in a STI or WRX?

 

yeah, was a WRX at the time

 

I was just thinking STI in reality, my bad. I wasn't aware there was that much of a difference between the two ECU's though. I know the STI DBW ECU will easily cope with mods at that power level.

I know Bob Rawle is running the STI DBW ECU at over 550bhp, heavily modified, without any issues. Hence my comment..... although it was tongue in cheek, as I didn't go as far as thinking about who you used.

 

haha yeah. biggest problem was trying to control the turbo and idle

 

Idle issues? What injectors you running then... hosepipes , or is it a MAF issue?

 

lol, was on 700's. But you guessed it, was to do with the maf not liking the size of the turbo.

 

I know somebody who had issues with a newage. I ended up causing an engine failure.
At the time that completly put me off running the simtek I had bought and I ended up selling it and buying syvecs.

Your correct in saying it only takes a couple of issues to get the rumour mill going and all of a sudden a products reputation can be ruined.

Plenty people running Alcatek these days

 

Thanks for so much information, I've learned a hell of a lot reading through all of this!!!Looks like Syvecs is way over my needs. When the car is back together, I'll chat through if an Alcatek is needed or stick with OE Ecu with you Martyn (thank you for the advise too!!!)

 

Can't you rescale the MAF on a WRX ECU!?...... right piece of junk then!

You should have bought the grown-ups version of the car mate.... the STI.

 

haha, was more to do with it not responding quick enough to the extra mass of the turbo so i understand, way over my head tbh
