Re: T4 ECU with Plastic Body

Just comparing the printed Firmware #'s and the Serial numbers between the brochure and the OP photo, it maybe that DTA have switched from one style to a completely moulded 'clam shell' type enclosure - cost probably comes into the equation although heat dissipation could be worse if 'all' plastic? ...

Re: T4 ECU with Plastic Body

Semantics Steve - English is the guys 2nd language! Upgrade . . . . as in change from a S60 to a new T4. In answer to the question a new T4 ecu will be billet aluminium - it says so here in the unit info sheet - https://www.dtafast.co.uk/dta_products/t4-ecu/ I believe, as Steve said the S40's were a...

That's been done before - more times than peeps like to admit? :lol:

Re: P8 in Fiat Fire, test coils, fuse blows

If you are seeing voltage drops of that magnitude you've something more than DTA tuning to worry about! The starter will pull the system volts down maybe a couple of volts max - say down to10.5v? so either your battery is approaching 'end of life' or you need one with greater capacity?

Re: hall effect sensor

As DTA specify a 5v rail for all sensor feeds, I would assume a 12v sensor would cause issues as the ecu is just looking for 0v - 5v square wave. The 5v rail should be regulated and independent of the 12v power feed that are more likely to be affected during cranking / cold starting.

Using S60 without injectors

May sound strange but I'd like to know - am I likely to damage anything in the ECU if I run it without injectors connected ie. Ignition only use but still datalogging with wideband input? As far as I can see, there is no 'facility' to 'turn off' anything electrically, except either by disconnection ...

Re: S40Pro Firmware 66.03 After Update to newest Version Engine not running....

My S60 was Hardware 2 and firmware v27 ! ! ! and DTA upgraded it to current version in 2022, so old to new is possible BUT the new software can't run on PC's with OS newer than XP (as I found out !) Not saying this is the problem, just pointing out the 'dealer' is incorrect with his statement! Oh an...

Re: A couple of Tech Questions

Just because you have 6 cop's doesn't preclude the use of wasted spark. I don't know the settings but its in the manual - it may point to a problem? It does seem a lot of timing for low rpm - is the crank trigger secure? and TDC correctly indentified? Thats the limit of my diagnostic skills!

Re: DTA T2 Airshifter Wiring

If the airshifter is the kit I elluded to, its pretty old (reliable) tech that relies on grounding of solenoid. I don't know how 'electrically noisy' the shifter circuit is / would be, so my thought is just isolate each other whilst keeping simplicity! Its an odd question really as the MRE kit has a...
