New block worries

Good to see it progressing again

Why you considering the change in ECU???

I want more control and reliability.
When at Dales we tested the map switch and it wasn't working so I wasn't getting a retarded map on nitrous. It turned out to be a wire cam loose in the ECU.
The other 2 are recommended by Roland and what he prefers to work with. I am thinking to letting him build the engine as he said for free and to map it on his dyno.

It's the right way the map it on the engine dyno, the omex will be cheaper than pectal, if you go for the omex consider going fully sequential injection which this unit can support. You will get a smoother running engine but you will need to fit the dizzy or the later front cover with a cam sensor

Ah, now you're getting technical!
I haven't the time in my life to fully understand this so will leave it up to you guys and enjoy the read.

I'll stick to hunting down new tyres that I desperately need.

O/T. 265/35/18 R888 at least £220 each!!!

give me a bell I have a man I think

Do you think you ran the normal NA igntion timing when the piston melted then?

Dale made the repair and I am confident it was working on track as it did on the rollers. Still a worry that this can happen.
On reflection not the greatest idea to rely that the map switches on nitrous activation. It would make more sense to make sure the nitrous only works if it's on the retarded map.

Such changes and safety measures will be put into place.

You need lights up on the dash to tell its its 100% working

[spitfire4v8]

Have a check (i don't do much omex work so can't remember exactly) but i don't think the 710 supports multiple maps so I'm not sure how you'd get a dedicated nitrous map without uploading a separate file to the ecu .. best to check now rather than after it's fitted ..

[Sardonicus]

Thing is Derek you have outputs for this sort of thing on MS2/MS3 and other ECU's you could have a relay switching NOS and warning lights etc soon as you trip the switch for the 2nd map any failures here and you wont power on the NOS solenoids lamp etc I still have a spare output even though I have switchable maps,shift-light & purge valve outputs populated already they are programmable for the very purpose you seek I agree you need some redundancy in place but dont over complicate matters and empty your pockets in the process

[DangerousDerek]

I am sticking with the MS2 guys.

[DangerousDerek]

Ready to go back to Roland at ACR.
Lets hope he sorts it properly. He made a very kind offer to build it for me for free.
The engine will also be tuned on his dyno when its done.





seems to take up a lot of space in a 1 series BMW!

Nice one Derek running soon then.

I will be happy to have it running at Christmas giving me time to getting miles on it and race ready for easter.

The car is getting trailered to Teeside next week to have a full MSA spec cage fitted.

Keep me posted on the drag dates Derek I fancy some next year along with a few others am sure

Sounds like you're in good hands Derek, looking forward to watching your high speed antics on the strip soon

We will have the usual meet at the pod and Shakey at least once.

I really hope i can convince that a journey to Yorkshire will be worth it.
York have a meeting mid summer that includes the Street Racer championship. Its a great meeting to come along either to RWYB or join in the racing. I think Neals car could stand a good chance of taking the £1000 prize money.

I would love to see a turn out of modified TVRs at ten of the best at Elvington. Its a fantastic weekend, with 1/4 mile drags, a short but testing handling course and the famous flying kilometre. Get to stretch the legs somewhat on that one!

What brought on the FIA roll cage decision? Those things aren't cheap.....

Now I am running mid 10's I need to comply with rules and regs in certain drag race classes. Also seems a good idea after my 124 mph spin at York earlier this year. Could have been much much worse.

You can never be too safe. Fire proof overalls etc, I assume you already have. I am giving them serious consideration for trackdaying.

I have to have the full kit now. Race suit, boots, gloves, helmet, arm restraints if roof is off, and a neck brace although I am going to look into a new helmet and HANS device.

The full cage, 6 point harness and the seat bolted to chassis bars and not just the shell floor complete the safety package. I have a fire extinguisher to hand but may have to consider a proper system in the engine bay.
