Nice job, don’t forget the oil…

5.3:1 Lsd / diff filed in a cupboard ready for use (& forgotten - with the 4.778:1), started tidying the workshop  made a dent in it and can see some floor (no photo's sorry BUT IT HASHAPPENED!) next job is (probably?) the welding table and altering & painting the tubular subframe  Rich. |

 tripped over another Tony Law manifold that I'm hopingto modify for the car.  as I've a tubular suspension subframe theis shouldn't be a problem with the collectors clashing as on a standard subframe / Mazda enginemount setup. other busness, been busy so no actual progress but I have bought an Rx8 gearbox with Vauxhall adapter-plate so hopefully I can build a hybrid of the Rx front / bellhousing & input shaft with the Mx5 tailhousing so keeping the ppf & origonal gearstick position - will be collecting the box this week so will have more to say about it later (if it'll work?  ) Rich. |

Idiot award time..... I already have a capable ecu, a DTA S40 but ideas of grandeor pushed me into buying a 'bigger' DTA S100 so now have even more options to ignore (like 16 hours of datalogging etc?) www.dtafast.co.uk/dta_products/s100pro-ecu/more tech & cost  anyway..... Rich. |

Rich. Nice! Well, if your an idiot, I'm an idiot too. Another reason I sent the ME442 back and went G4X was the logging aspect of things, more logs, faster processor, on board logging, high logging resolution and rates as well good software to analyse the logs (ME was just a spreadsheet so you'd need other software) is very near the top of the list for me when doing a bit of tuna diy, What else do we have to go on unless we give the keys to the OH and sit in the passenger seat shouting instructions and having to answer questions like "how much did that cost?".  Whats your strat for tuning equations, you going to still run alpha-n (I assume the vaux tps is variable?) or do you predict your plenum will give you a stable map reading to run speed density? |

I'm looking at K.I.S.S t start with so tps only, the standard Vauxhall tps (Bosch) is adjustable but I'm not using the standard manifolding or tb and I have a P&G contactless tps so hopefully a 'clean' signal - should be for the price I'm hoping the airbox / plenum will quieten the inducton and also help feed 'cooler' air the the intake, if it's sealed sufficient to run a 'map' sensor then that'll be a bonus but not a problem if not... this ecu has possibly too many options for my (simple?) needs but has the future covered if I decide to get silly (4 wheel speed-sensors for traction control?)

Rich. Gotcha, yeah clean signal is really, really key. I've seen you can pin into the OE TPS harness but I decided to avoid that, a few people have had issues with TPS noise and just 1.5-2% throttle error is a lot more significant than a lot of people realise on ITBs. Sure, I gathered its not really a primary concern for the plenum but could be a nice bonus if you plan to run an IACV for idling etc. I've hooked up all my vacuum lines now but I'm yet to start the car (waiting on a radiator) so gonna see what I get. Your right about the amount of options but theres also so much stuff buried in the software that can be used for many different purposes. One I found as a set of "virtual input/outputs" where you could create a logical condition to turn things on and off. I was mucking about with it and found a way to run two fuel tables based on a conditonal input so if the TPS input was sub 1.5%, rpm <3000 and a stable map reading of somewhere in the usual idle range then it can switch to a MAP based fuel table which could be useful. You could also link this or something similar to a button (ie repurpose the AC switch), again very useful if you have a unique setup (ie. a switchable mapping for NOS  ). |

I believe an acv / iacv setup is the antichrist with an itb setup. itb's should be 'ballanced' cylinder to cylinder and an air bypass removes this (can run a rich cylinder weak as an extreme). the main benefit of an icv is for the initial coldstart but those of us old enough to remember carburettors would just cover the throttle foe a few seconds / minute untill stability occurs I'm wiring the car from scratch, the ecu can run switchable maps amongst other wizardry  Rich. |

Sadly I'm old enough to have owned a car with a manual choke and changing the points as part of a service schedule like you would oil lol. So yeah, moar throttle works for me I'm wiring the car from scratch, the ecu can run switchable maps amongst other wizardry Rich. Lovely |

When I first fitted Dellortos to my XE I used the original Bosch Motronic ECU for ignition. The airbox was sealed so I fitted the original AFM into the air intake tube, and used the original distributor and TPS together with the VX loom less all the fuelling wiring etc.
I managed to drive UK/France and back without problems whilst saving for a DTA ecu.
Bit Heath Robinson, but it worked.

Had a play with the S100 ecu, I can see plenty of possible 'oops' moments here BUT also plenty of great options obviously I'm not going to use all of these but launch control, 4 wheel traction control (wet & dry?) are easily connected on the 5 due to oem abs sensor mounting / wiring thats retrofittable - just need to find sensors now.... more complications...

tripped over another Tony Law manifold that I'm hopingto modify for the car. as I've a tubular suspension subframe theis shouldn't be a problem with the collectors clashing as on a standard subframe / Mazda enginemount setup. other busness, been busy so no actual progress but I have bought an Rx8 gearbox with Vauxhall adapter-plate so hopefully I can build a hybrid of the Rx front / bellhousing & input shaft with the Mx5 tailhousing so keeping the ppf & origonal gearstick position - will be collecting the box this week so will have more to say about it later (if it'll work? ) Rich. I've been slacking and not keeping up with the thread  so I have to ask - what is the difference/benefit with this Tony Law manifold? |

so I have to ask - what is the difference/benefit with this Tony Law manifold? so.... this 'newer' manifold and the 'older' one I modifird to fit the Mazda 1.6L engine? realistically nothing. its basically the same manifold and actually a little small pipe diameter (as ~41mm od) for the 2L Vauxhall engine so probably stay as spares (& a reminder to check!) I'm looking for a manifold with ~45mm od primaries so probably new is in my future (I've already gone mental with the budget so why not?) subject of udget, just bought a professionally made ecu-engine loom so thats less work BUT also will need altering to fit the car Rich. |

photo update time, just to s hitpost a bit more....  my 'old' Dta S40 and 'new' DTA S100 ecu, the S40 was good enough to run the XE but the S100 has a 'few' more options and outputs  I've also bought a pro-built engine loom (excuse the photo's, they're from it's advert)  the loom is 'stand-alone' so carries fuelpump and rad / cooling fan relays (more can be added like wb02 sensor heater power feed - usefull as the ecu / ignition can be 'on' but you're not burning out an expensive 'LSU4.9' sensor).  the 'interesting' bit, these wires will terminate in switches to operate their functions, obviously at another 'end' the loom will connect with 4 x wheel sensors (I'm hoping to use abs sensors as mx5's had this as option & standard fit depending on age - wondering how few 'teeth' I can use on the abs 'rings' but still carry sufficient resolution ) and obviously the ecu needs to do it's part... too many ideas but Launch and traction control would be realy nice 'extras' Rich. |

okey, been tidyin the workshop and tripped over a standard Vauxhall 'XE' 2L conrod so decided to weigh it and compare to the ebay (chineese?) 'Nevlock steel / forged rod and a 'Plankl' narrow-journal / longer centre length conrod...  652g with bolts (and rust!), these are good rods, accepted as 'safe' past 7.000rpm but getting old now....  578g (no b/e bolts fitted as I forgot!) but a direct replacement for the standard item.  480g with bolts, this is a lovely piece, shame it needs different pistons and a specific (non-standard) crankshaft to use  so, scientific experiment over & back to tidyup.....
