Hi this is my 1st cosworth and im trying to put my new chip in but cover want go on as the chip is to big (HELP ME PLZ)

Thanks John

 

Most likely a wrong chip then.
What type of ecu is it? L1, L6, L8, P8? Check: http://bigturbo.co.uk/main1.htm
Who manufactured the chip? Maybe add a photo?

 

Its a l8 from a 4X4.

 

Its a L8 from a 4X4. How can i add photo.

 

LOL then it's not the chip it should be if that at all, the chip is a rectangular shape and has alot of legs, this simply sits in a socket on the PCB and then the cover screws in via 4 screws.

To post the image you need to have it stored online and then you post the link to the image using [IMG] coding.

Ok i think this how to do it..

<a href="http://www.flickr.com/photos/59696061@N02/5510439604/" title="new on left by JChannon, on Flickr"><img src="http://farm6.static.flickr.com/5097/...f92954f01c.jpg" width="500" height="333" alt="new on left" /></a>

 

Looks to me like it should fit just fine.

In what way is it too big?

 

Its to high the lid sits up by a good 5mm

 

Is the "New on left" the Evolution chip on top of the Superchip for size comparison or is the one on the left the new chip itself?

Martin

 

Well what help do you want then if thats what happens?

Either cut a hole in the lid or get another chip, i'd be going for the later personally.

Surprised Stu would supply something that doesnt fit, there must be some misunderstanding somewhere I would think. Phone him tomorrow.

 

Yes new one on the left. I was thinking i would have to take some think out to make it fit. I will have to contact them and see what they think.

 

Morning,
The chip should have been supplied with instructions explaining how to modify the ECU's daughterboard to facilitate fitment. Did you buy it new?

 

Hi i got the chip from you mate.

Its well big im going to have a look at the instructions to see if i missed something.

 

Hi, Please accept my appologies if any of teh instruction sheets are missing.

Please E-Mail us with your chip number and we can email over any instructions that are missing sir.

 

The number on the chip is 5283.

 

Will the pistons i have found on ebay be ok for my sierra the Item number is 290536645333

 

Wiseco's are good pistons and RS200DELL is a good seller (derrick scarrow) but they are 7.8:1 so might not match that chip you just bought.

 

Hi i got Stewart Sanderson to help me out and he was very helpful. I have a gt35 turbo with external wastegate big intercooler and radiator and this what he told me to get and i did. I trust him 100%. See what you think.


Ok, top of my head, If I were to take a standard YB and make it suitable for your turbo and 400+BHP I would lower the compression to 7.8:1 with pocketed pistons, fit a 3 port breather system, ported head and cometic headgasket. Then we would fit an uprated intercooler and radiator, finally, you’re ready to bolt on these parts:

Necessities:
BD 16 inlet cam.
Double valve springs so we can rev her to 8000rpm.

New followers BECAUSE we are going to rev her to 8000rpm
Plenum spacer to improve airflow through the inlet trumpets.

Bosch 044 pump and adaptor to fit direct to your car.
Engine & gearbox mounts to stop movement wrecking your DS joints.

3 bar map sensor:
83lb injectors

Dump valve: (necessity for GT series turbos)

Chip to your own spec

 

Well then bearing that in mind, yes those pistons will be fine.

 

PS

and with that sort of money spent, I would be taking it back to Stu for a live map when its finished.

 

Hi he is in Blackpool and im in west sussex long way to go. Do you think i should do the con rods to. And is there a good and a bad valve set. Also looking for a complete gasket set. Could you help me with this.

 

Thanks John

 

Yes there are good and bad valves, good condition original ones are a very good option as they are high quality in the first place.

I'd do the drive if I were you, its worth it to get the car running right.

Standard rods should be fine if they are in good condition.

Get a WRC gasket, not worth messing around with anything else now they have come down in price.
Martin hadland is normally good for prices on those IIRC

 

Sorted saved some cash. I will have a look for them from Martin hadland. Thanks for all you help

 

Hi Im thinking your right mate i will be going to blackpool. Get it done right.
