Eurospec, 7202 ECU and a reflash

[Nutter_John]

Come to cumbria i have the perfect bit of road 5 mins from my house

I thought that was now a river


Don has a nice piece of private road near his unit , just as I do .. this makes it a bit easier

[Atik]

the 7201 is a totally different ball game so lets not confuss the issue

I recon you should see around 305 bhp

I know

305 you reckon? I was hoping to maybe see around 310, but then I thought that my pistons might give up way before then. Ben aborted one of my previous dyno runs as the pistons almost gave up at 236bhp at the wheel. Well, lets see what next week brings.

There is a few roads up here I can think of. John you fancy a trip to Aberdeen?

[miller]

Just curious, how do you know your 'pistons' werent happy at 236hp?

Keeping an eye on this thread with interest as its the cross roads im at regarding vipec or just flashing.

vipec will give you far better performance than re-flash of stock ( based on the better control of the vipec )

I'm the same Mike.

So why go re flash John if Vipec is better?

So why go re flash John if Vipec is better?

Because you have to pay for VIPEC before you even start with the mapping costs

But if you get better results then the extra cost is worth it. IMO

So why go re flash John if Vipec is better?

1) To push the envelope / explore alternatives
2) For reasons / considerations concerning comparable costs

[Nutter_John]

The vipec will allow the mapper to get better control of the car and push closer to the limits . it will alos allow the ecu tables to be update on the fly so real time tunning is possible 1000's times with out issues . All these features come at a cost so for example a Vipec will set you back around 1.5k .

The stock ecu will allow you to alter it's tables but to do so you must switch the car off each time , this means you can not map on the fly ( slows down the mapping ) . If you look aorund they have done great things with the EVO stock ecu and can now do live mapping , anti lag , Lauch control , flat shift , multi maps - but this is were people have re-wrote the internal code of the ecu . I very much doubt that we will see this level happen on the vr4 , One issue that will hit some people is that there is a limit on the number of times the ecu can be writen !!!
cost wise you are looking at around £300 ish to remap


So the vipec may get you 15% more out of the same engine , but it costs 5 times the price , but gives you 10 times the feature

I would go with the vipec every time but on my evo I have reflashed the rom as it suits where I am now !!

[apeman69]

And anybody at a cross roads who thinks that the extra cost is worth it for the extra performance should turn right towards the Vipec.

[Nutter_John]

One thing to mention is that the price that Ben is doing for the vipec mapped is very very good value

[Atik]

Just curious, how do you know your 'pistons' werent happy at 236hp?

Cos Ben told me In all honesty, I'm not actually sure, but he told me that when I dyno'd the car earlier this year after I fitted the Emanage.

I'm going via the reflash ECU route purely because the Vipec would be too much for me, in both cost and functionality. All I am looking for is to tune the car to a point and leave it there. I'm not looking for 'on-the-fly' tuning or the level of detailed tuning afforded by the Vipec. Just want to improve my maps and control the various parameters so that the car is maximising its potential.

So it sounds like I should start saving for a Vipec then.

And hope, like the rest of us with autos, that it can be proven to work as desired.

[Nutter_John]

Will be a case of finding the comms used from the auto ecu to drop torque during a gear change and then getting the Vipec to do the same .

When Caveman had his autronic done they left the stock ecu in place to make sure there were no issues with the auto box , but I doubt it pulled torks when changing gear .

[aboo]

Thats the thing once I get the inter cooler I want I'm into the next stage so want to get whats best for the auto. Map2, piggyback, vipec or reflash?

Not to bothered with cost just whats best.

I Know that re flash is best value but we dont know what we can do with it yet from the auto side of things.

Thats why I'm asking the questions.

[Nutter_John]

well as yet the Vipec has not been done on an auto , so until then I would say a remap would be best .

Hold you breath until Atik;s is done as we need to see some figures

[aboo]

Thanks John. I know Atiks is a manual but will see what happens with his & take it from there.
