Hi ive got a 20v corrado running on q peng at the moment. what sort of costs are involved for a DTA ecu. I would have to fit myself as im too far away. Would i have to make my own loom etc Do you have any information on them? Im also looking at oem management but not sure what to go for for the best. My aim is to run around mid 300's eventually so is dta over kill?
S40 ecu is 450+vat plus sensor plug connector. You would need to adapt to the wiring loom yes. Its a flexible ecu to map.
Hi thats sounds reasonable. Would modifying a loom be hard? Would it be a standard loom id modiffy or do i have to build one from scratch? Do you think the q peng loom could be adapted? reason i ask is i could probably copy the qpeng loom thats on it at the moment. I know these are silly questions really as it depends on how much i can do myself. Are base maps available as its basically just a standard AUM code engine at the moment but would like to get it running before i started making changes to the engine
also found this: http://www.racenet.gr/dta-s40-pro-harness/ Looks like it would make the wiring easier. Im an electrician but not played about with car electrics much but know the basics.
not seen that link before.. looks good.. and price is appealing. If you have qpeng wiring now, then you have your required sensor wires in one spot, so reterminating vs start over is your call
Thanks. That sounds great and just what I'm after really. I've a few more questions but Il give you a call if thats ok as I will probably order it at the same time
ECU came saturday morning thankyou. Are they supposed to come with a comms lead for your computer or do you have to buy them separate? Cheers
Can I just ask why you would recommend a S40 over a E48EXP? I am doing the same conversion in a Mk1 golf and have the E48 as thats what I was recommended at the time. I only ask as a friend of mine had problems with his E48, two injectors firing at the same time aparently dta said this is how they operate???
From what I have read and picked up dta fires the injectors in batches of 2. I think exp48 is an older version of the s series Ecu's.
Batch firing of injectors is used on many of the less expensive standalone ecu's. Hardware cost within the ecu being a factor governing this. You pay more you get greater control generally.
I see. Surley two injectors firing at once will just cause the engine to over fuel!. It also sounds like a tappet is out when they fire together. What kind of ecu would be a better more adjustable unit that wouldn't do this?
