iv just bought a td05 and a decat downpipe for my 95wrx wagon , do i need to change anything else to get the most from it ?

cheers in advance

 

Need 550cc injectors and a New Age TMIC or FMIC+IK, before the remap. Then you'll give the turbo the chance to make the 330-350bhp it's capable of.

I assume you already know about your ECU options..?

 

ecu options ?
iv fitted them and it goes like stink but has about a week of lag then goes ? im using the actuator from my td04 could this be the cause ?
also iv just been for a drive and it pulled to 125 then it was registering 17psi and hit fuel cut ........????

help !

 

And no doubt its detting your engine into oblivion, wait for the dreaded big end rattle if the pistons dont go first

I'll put it another way take your toilet, add a bigger water tank, it fills up more, your toilet overflows when you flush so you have to put a bigger bowl in to compensate, without compensating you will flood your house and have a HUGE bill, thats whats happening here, your engine cannot compensate for what you have done, you have changed the characteristics of the air/fuel ratio as well as going outside the standard ecu map, it wont be happy, and they normally dont stay unhappy long before they go BANG!

speak to major_sarcasm, he is your man to supply (an can fit) a scoobychip for 93-96 im pretty sure you can get your wagon sorted. This will set new parameters & settings for the car to work to & give very good & safe gains. However the engine & parts do need to be in good working order otherwise the chip will highlight any weaknesses. But once fitted you will be a happy bunny & the car will run very well more info for you here:

Sorry for the hijack !!!

My mate also has a td05 and a brand new decat which he has bought for his 1995 wrx wagon,but his is auto transmission. He has bought a new ecu with a polar performance chip which was fitted to a saloon 95 wrx,which had a td05 fitted as std,and wants me to fit it for him on monday, but i am just a bit wary as the most power that came from an auto wrx that i am aware of is 240 bhp.With the chip and other mods ie:walbro,full decat ,etc,just wondering if the box can take it.
Legacy twin turbo's auto box can take 280 bhp all day long,and i'am hoping its the same for the impreza.

 

OP, I assume you've just fitted the TD05 16g and decat d/p - and nowt else?

You need to match the TD05H 16g with an ECU intended for it. The Z4 (260PS) or the 6K (275PS) are the ones to go for.

Or has already been mentioned, get a Polar Performance chip (or already PP-chipped ECU). Good for up to c.280bhp with a decat... plus the fuelling tables have been sorted so it runs slightly on the rich (safe!) side.

Or best of all, get a bespoke custom remap on ESL Live....

Whatever, you should address this asap, or as has already been stated, engine won't be long for this world. You're running this bigger turbo on the (now underfuelling!) wagon's 220PS rated ECU - as it was mapped for the smaller std fit TD04L!!!...

 

can i just put the td04 back on with the decat ?

 

just put the td04 back on and all seems well now just had a look and i have the 3b ecu

 

You should be okay with the correct TD04 and a decat - the AFR's will have been brought back within the 3B ECU's capabilities...

 

good goooooddddd

i personally wouldnt bother with the ebay chips. speak to major sarcasm. he has chips with a map which is the same as the scoobyecu/polar chips that have been tried and tested for years and years.

 

Totally agree with the above ^^^

OP, I take it if you do get a PP chip, you're going to reinstate the TD05 16g to make the most of it? Most PP chips knocking about have a map for the more popular TD05 - although there is one designed for the TD04 too...

 

indeed i will be
